The enqueue operation on the Queue ADT adds a new item to the back of the queue where the dequeue operation removes and returns the item from the front of the queue. Now consider an initially empty queue and find the final output for the following sequence of queue operations: enqueue(7); enqueue(9); enqueue(1); dequeue(); enqueue(8); dequeue(); dequeue(); enqueue(6); enqueue(3); dequeue(); enqueue(2); enqueue(1); dequeue(); Solution import java.util.*; java.io.*; java.lang.*; class Queue { private ArrayList list; public Queue() { list = new ArrayList(); } public void enqueue(Object object) { if(list.isFull()) System.out.println(“Queue overflowedâ€); else list.add(object); } public Object dequeue() { if(list.isEmpty()) System.out.println(“Queue underflowâ€); else return list.remove(list.size() - 1); } public boolean isEmpty() { return list.isEmpty(); } public Object front() { return list.get(list.size() - 1); } public Object back() { return list.get(index); } public void clear() { list.clear(); } } class QSample { public static void main(String args[]) throws Exception { Queue q=new Queue();   while(true) { System.out.println(\"\ \\t QUEUE \"); q.enqueue(7); q.enqueue(9); q.enqueue(1); q.back(); q.dequeue(); q.enqueue(8); q.dequeue(); q.dequeue(); q.enqueue(6); q.enqueue(3); q.dequeue(); q.enqueue(2); q.enqueue(1); q.dequeue(); System.out.println(\"Exit\"); } } } The Final output is : 3 2 1 .

In java , I want you to implement a Data Structure known as a Doubly.pdf
In java , I want you to implement a Data Structure known as a Doubly-Ended-Queue. it is a
“fair” data structure in that it implements a FIFO (First In First Out ) behavior. As such, it is
often used to implement various wait lists in computer systems. For example, jobs waiting to use
the CPU, jobs waiting for a printer, jobs waiting to be placed into RAM for execution. In short,
whenever we want a fair strategy for waiting we use queues.
A DEQUE (Doubly-ended-queue) is a related data structure. Although similar to a Queue, it
differs in that it allows for insertions AND deletions from either end of the list (both the front
and the rear).
Your implementation MUST use a doubly-linked-list implementation. You may not use a static
array implementation.
Thus, a Deque is a List but it is one which only concerns itself with the first and last positions for
any insertion or deletion. The 6 operations supported are :
public void insertFront( int item ) - insert the given item (as a node) into the first position of the
Deque.
public void insertRear( int item ) - insert the given item (as a node) into the last position of the
Deque.
public int deleteFront( ) - delete and return the element stored in the first node of the Deque.
public int deletRear( ) – delete and return the element stored in the last node of the Deque.
public boolean isempty( ) - returns true if the Deque is currently empty or false if it is not.
public void printDeque( ) - print the integers from the list, one per line, from the first element
through to the last in order.
Classes
Your program must implement the following 3 classes. public class dequeDriver
This class will contain your program’s main method. It will need to declare a deque object and
process input as indicated below.
Your program should prompt the user for the path of an input file. It should open the file for
input and process it line by line. Each line of the input file will have one of the following forms.
PR
IF
IR
DF
DR
The meanings of each input is as follows:
PR - print the current contents of the deque from front to rear using the printDeque( ) method of
the deque object.
IF - insert the given int value into the front of the deque.
IR - insert the given int value into the rear of the deque.
DF - delete the front value from the deque.
DR – delete the rear element of the deque.
Below is an example input file that your program should be able to process.

Writing native bindings to node.js in C++
Talk given at JSFoo Pune 2012
http://jsfoo.in/pune2012/schedule
Description (Part A) In this lab you will write a Queue implementati.pdf
Description (Part A) In this lab you will write a Queue implementation called CoolQueue, which
closely matches the java.util.Queue collection, except with fewer methods. Test code is provided
that allows you to compare your queue to the one in java.util.Queue, which you can assume is
completely correct.
Getting Started
Create a project called Lab9 and download following files:
QueueInterface.java
TestProgram.java
CoolQueue.java
Fill in the supplied CoolQueue.java to make it implement the provided QueueInterface methods.
Then use the TestProgram to verify that your code works. Here are the methods in the interface:
public interface QueueInterface {
// Add object onto rear of queue
public abstract boolean add(E item);
// Remove object from front of queue // Throws NoSuchElementException if empty
public abstract E remove();
// Peek object from front of queue // Throws NoSuchElementException if empty
public abstract E element();
// Check for empty
public abstract boolean isEmpty();
// Returns size
public abstract int size();
// Clears queue
public abstract void clear();
// Various searches
public abstract boolean contains(Object o);
// Override toString
public abstract String toString(); }
Instructions
Inherit the interface provided above.
The Queue is a generic data structure, so declare an LinkedList.
HINT: You should use the first entry or head of the LinkedList as the front of the queue.
HINT: You should use the last entry or tail of the LinkedList as the rear of the queue.
You must not use add(), remove(), or element() in the LinkedList object.
You must implement toString() first, format is the same as LinkedList.toString().
Incremental development, so test one method at a time.
Review the TestProgram to see what is tested by each test number, 1 through 7.
Below is the CoolQueue.java:
import java.util.LinkedList;
import java.util.NoSuchElementException;
class CoolQueue implements QueueInterface {
// Underlying data structure
// Default constructor
}
Below is the TestProgram.java:
import java.util.LinkedList;
import java.util.NoSuchElementException;
import java.util.Queue;
import java.util.Random;
public class TestProgram {
static Random random = new Random();
public static void main(String[] args) {
// Make a Java stack
Queue javaQueue = new LinkedList<>();
// Make a student stack
CoolQueue coolQueue = new CoolQueue<>();
// Which test?
int testNumber = Integer.parseInt(args[0]);
switch (testNumber) {
case 1: // testAdd
System.err.println(\"testAdd: verifying add() method\");
pushRandom(javaQueue, 10);
pushRandom(coolQueue, 10);
System.err.println(\"Java Queue: \" + javaQueue);
System.err.println(\"Cool Queue: \" + coolQueue);
break;
case 2: // testRemove
System.err.println(\"testRemove: verifying remove() method\");
pushRandom(javaQueue, 10);
pushRandom(coolQueue, 10);
// Legal removes
for (int i = 0; i < 10; i++) {
System.err.printf(\"javaQueue.remove(): %4s, coolQueue.remove(): %4s\ \",
javaQueue.remove(), coolQueue.remove());
}
// Queue e.

CST 280 In-Class Practice – Week 13
Manually determine the configuration of the priority queue (stored as a heap) created
by the following operations. Trace the following logic and define the output:
enqueue(7);
enqueue(17);
enqueue(2);
enqueue(5);
enqueue(22);
enqueue(19);
enqueue(6);
enqueue(11);
enqueue(13);
write the queue contents
dequeue and write front item
enqueue(15);
enqueue(8);
dequeue and write front item
dequeue and write front item
enqueue(24);
enqueue(14);
write the queue contents
Part 2
Then, verify the output by implementing the algorithm by rewriting the priority
queue demonstration program discussed in class. Files needed:
testPQueue.cpp pqType.h heap.cpp
Deliverables
• This cover sheet (with your names on it)
• Driver source code and output for verification program exectution.

CST 280 In-Class Practice – Week 13
Use this page as a worksheet to sketch the progression of the elements up to the first
split for the QuickSort algorithm. Use the middle array element as the split value:
15 34 99 42 11 41 66 23 55 93 48
Next, access the file quickSort.cpp from the course web page. Tailor the program
by entering the array values above in place of the integer values used for an in-class
demonstration. Be sure to adjust the index range to match the size of this array.
Remember that the parameters to the QuickSort algorithm are starting and ending index
values, not the size of the array.
Next, insert code to demonstrate the state of the array after the first split. This should
verify what you did by hand above. Insert the following code at various points within
the partition function to “see” the array at various stages of processing:
for (int i = start; i <= end; i++) // <== ADD
cout << set[i] << ' ';
cout << endl;
Insert the code at these positions:
int partition(int set[], int start, int end)
{
int pivotValue, pivotIndex, mid;
mid = (start + end) / 2;
swap(set[start], set[mid]);
pivotIndex = start;
pivotValue = set[start];
ç HERE
for (int scan = start + 1; scan <= end; scan++)
{
if (set[scan] < pivotValue)
{
pivotIndex++;
swap(set[pivotIndex], set[scan]);
}
ç HERE
}
swap(set[start], set[pivotIndex]);
ç HERE
return pivotIndex;
}
Finally, identify the line that matches what you concluded above.
Deliverables:
Deliver the following for this assignment:
• This work sheet with a sketch of the array first split
• Program source code with required change
• Program output demonstrating array configuration after first split .
A topology of memory leaks on the JVM
While most bugs reveal their cause within their stack trace, Java’s OutOfMemoryError is less talkative and therefore regarded as being difficult to debug by a majority of developers. With the right techniques and tools, memory leaks in Java programs can however be tackled like any other programming error. This talks discusses how a JVM stores data, categorizes different types of memory leaks that can occur in a Java program and presents techniques for fixing such errors. Furthermore, we will have a closer look at lambda expressions and their considerable potential of introducing memory leaks when they are used incautiously.
Implement the ADT stack by using an array stack to contain its entri.pdf
Implement the ADT stack by using an array stack to contain its entries. Expand the array
dynamically, as necessary. Maintain the stack’s bottom entry in stack[stack.length – 1].
Your Stack class must implement StackInterface (provided). You may use ArrayStack.java
(provided) as the starting point for your implementation.
You must implement a comprehensive set of unit tests using the main() method (and private
utility methods) in ArrayStack.java.
ArrayStack.java

private T[] stack; // Array of stack entries
private int topIndex; // Index of top entry

private static final int MAX_CAPACITY = 10000;
public ArrayStack()
{
this(DEFAULT_CAPACITY);
} // end default constructor
public ArrayStack(int initialCapacity)
{
checkCapacity(initialCapacity);
// The cast is safe because the new array contains null entries
@SuppressWarnings(\"unchecked\")
T[] tempStack = (T[])new Object[initialCapacity];
stack = tempStack;
topIndex = -1;
initialized = true;
} // end constructor
// < Implementations of the stack operations go here. >
// < Implementations of the private methods go here; checkCapacity and
// checkInitialization are analogous to those in Chapter 2. >
// . . .
} // end ArrayStack
StackInterface.java
public interface StackInterface
{
/** Adds a new entry to the top of this stack.
@param newEntry An object to be added to the stack. */
public void push(T newEntry);
/** Removes and returns this stack\'s top entry.
@return The object at the top of the stack.
@throws EmptyStackException if the stack is empty before the operation. */
public T pop();
/** Retrieves this stack\'s top entry.
@return The object at the top of the stack.
@throws EmptyStackException if the stack is empty. */
public T peek();
/** Detects whether this stack is empty.
@return True if the stack is empty. */
public boolean isEmpty();
/** Removes all entries from this stack. */
public void clear();
} // end StackInterface

The Financial Management Decision Process What are the three types of.docx
The Financial Management Decision Process
What are the three types of financial management decisions?
For each type of decision, give an example of a business transaction that would be relevant.
Solution
Three types of financial management decisions are as under:
1. Investment decision
Investment decisions are also called capital budgeting decisions. These decisions involved careful selection of assets / project to be purchased or invested.
Example: Purchasing a machine.
2. Financing decision:
After deciding about the investment, next big decision is arranging the funds for the investment. In this decision management decides the source of finance like : debt, Equity etc.
Example: Issuing common stock to raise funds.
3. Dividend decision:
When Management has invested the fund in the business it will probably earn profits. And now they have to take one more decision that is distributing of profits that is also called as dividend decision.
In this decision they decided how much amount of profits is to be distributed as dividend and how much is to be retained for business.

The Federal Reserve attempts to keep prices stable and unemployment lo.docx
The Federal Reserve attempts to keep prices stable and unemployment low. Is there are a contradiction in these objectives? Describe the monetary policy tools that are available to the Federal Reserve to achieve these objectives.
Solution
The Federal Reserve, like many other central banks, is an independent government agency but also one that is ultimately accountable to the public and the Congress. The Congress established maximum employment and stable prices as the key macroeconomic objectives for the Federal Reserve in its conduct of monetary policy. The Congress also structured the Federal Reserve to ensure that its monetary policy decisions focus on achieving these long-run goals and do not become subject to political pressures that could lead to undesirable outcomes. So, members of the Board of Governors are appointed for staggered 14-year terms and the Chairman of the Board is appointed for a four-year term. Elected officials and members of the Administration are not allowed to serve on the Board.
The Federal Reserve does not receive funding through the congressional budgetary process. The Fed\'s income comes primarily from the interest on government securities that it has acquired through open market operations. Other sources of income are the interest on foreign currency investments held by the Federal Reserve System; fees received for services provided to depository institutions, such as check clearing, funds transfers, and automated clearinghouse operations; and interest on loans to depository institutions. After paying its expenses, the Federal Reserve turns the rest of its earnings over to the U.S. Treasury.

Talk given at JSFoo Pune 2012
http://jsfoo.in/pune2012/schedule
Description (Part A) In this lab you will write a Queue implementati.pdf
Description (Part A) In this lab you will write a Queue implementation called CoolQueue, which
closely matches the java.util.Queue collection, except with fewer methods. Test code is provided
that allows you to compare your queue to the one in java.util.Queue, which you can assume is
completely correct.
Getting Started
Create a project called Lab9 and download following files:
QueueInterface.java
TestProgram.java
CoolQueue.java
Fill in the supplied CoolQueue.java to make it implement the provided QueueInterface methods.
Then use the TestProgram to verify that your code works. Here are the methods in the interface:
public interface QueueInterface {
// Add object onto rear of queue
public abstract boolean add(E item);
// Remove object from front of queue // Throws NoSuchElementException if empty
public abstract E remove();
// Peek object from front of queue // Throws NoSuchElementException if empty
public abstract E element();
// Check for empty
public abstract boolean isEmpty();
// Returns size
public abstract int size();
// Clears queue
public abstract void clear();
// Various searches
public abstract boolean contains(Object o);
// Override toString
public abstract String toString(); }
Instructions
Inherit the interface provided above.
The Queue is a generic data structure, so declare an LinkedList.
HINT: You should use the first entry or head of the LinkedList as the front of the queue.
HINT: You should use the last entry or tail of the LinkedList as the rear of the queue.
You must not use add(), remove(), or element() in the LinkedList object.
You must implement toString() first, format is the same as LinkedList.toString().
Incremental development, so test one method at a time.
Review the TestProgram to see what is tested by each test number, 1 through 7.
Below is the CoolQueue.java:
import java.util.LinkedList;
import java.util.NoSuchElementException;
class CoolQueue implements QueueInterface {
// Underlying data structure
// Default constructor
}
Below is the TestProgram.java:
import java.util.LinkedList;
import java.util.NoSuchElementException;
import java.util.Queue;
import java.util.Random;
public class TestProgram {
static Random random = new Random();
public static void main(String[] args) {
// Make a Java stack
Queue javaQueue = new LinkedList<>();
// Make a student stack
CoolQueue coolQueue = new CoolQueue<>();
// Which test?
int testNumber = Integer.parseInt(args[0]);
switch (testNumber) {
case 1: // testAdd
System.err.println(\"testAdd: verifying add() method\");
pushRandom(javaQueue, 10);
pushRandom(coolQueue, 10);
System.err.println(\"Java Queue: \" + javaQueue);
System.err.println(\"Cool Queue: \" + coolQueue);
break;
case 2: // testRemove
System.err.println(\"testRemove: verifying remove() method\");
pushRandom(javaQueue, 10);
pushRandom(coolQueue, 10);
// Legal removes
for (int i = 0; i < 10; i++) {
System.err.printf(\"javaQueue.remove(): %4s, coolQueue.remove(): %4s\ \",
javaQueue.remove(), coolQueue.remove());
}

CST 280 In-Class Practice – Week 13
Use this page as a worksheet to sketch the progression of the elements up to the first
split for the QuickSort algorithm. Use the middle array element as the split value:
15 34 99 42 11 41 66 23 55 93 48
Next, access the file quickSort.cpp from the course web page. Tailor the program
by entering the array values above in place of the integer values used for an in-class
demonstration. Be sure to adjust the index range to match the size of this array.
Remember that the parameters to the QuickSort algorithm are starting and ending index
values, not the size of the array.
Next, insert code to demonstrate the state of the array after the first split. This should
verify what you did by hand above. Insert the following code at various points within
the partition function to “see” the array at various stages of processing:
for (int i = start; i <= end; i++) // <== ADD
cout << set[i] << ' ';
cout << endl;
Insert the code at these positions:
int partition(int set[], int start, int end)
{
int pivotValue, pivotIndex, mid;
mid = (start + end) / 2;
swap(set[start], set[mid]);
pivotIndex = start;
pivotValue = set[start];
ç HERE
for (int scan = start + 1; scan <= end; scan++)
{
if (set[scan] < pivotValue)
{
pivotIndex++;
swap(set[pivotIndex], set[scan]);
}
ç HERE
}
swap(set[start], set[pivotIndex]);
ç HERE
return pivotIndex;
}
Finally, identify the line that matches what you concluded above.
Deliverables:
Deliver the following for this assignment:
• This work sheet with a sketch of the array first split
• Program source code with required change
• Program output demonstrating array configuration after first split .
A topology of memory leaks on the JVM
While most bugs reveal their cause within their stack trace, Java’s OutOfMemoryError is less talkative and therefore regarded as being difficult to debug by a majority of developers. With the right techniques and tools, memory leaks in Java programs can however be tackled like any other programming error. This talks discusses how a JVM stores data, categorizes different types of memory leaks that can occur in a Java program and presents techniques for fixing such errors. Furthermore, we will have a closer look at lambda expressions and their considerable potential of introducing memory leaks when they are used incautiously.
Implement the ADT stack by using an array stack to contain its entri.pdf
Implement the ADT stack by using an array stack to contain its entries. Expand the array
dynamically, as necessary. Maintain the stack’s bottom entry in stack[stack.length – 1].
Your Stack class must implement StackInterface (provided). You may use ArrayStack.java
(provided) as the starting point for your implementation.
You must implement a comprehensive set of unit tests using the main() method (and private
utility methods) in ArrayStack.java.
ArrayStack.java
public class ArrayStack implements StackInterface

private T[] stack; // Array of stack entries
private int topIndex; // Index of top entry
private boolean initialized = false;
private static final int DEFAULT_CAPACITY = 50;
private static final int MAX_CAPACITY = 10000;
public ArrayStack()
{
this(DEFAULT_CAPACITY);
} // end default constructor
public ArrayStack(int initialCapacity)
{
checkCapacity(initialCapacity);
// The cast is safe because the new array contains null entries
@SuppressWarnings(\"unchecked\")
T[] tempStack = (T[])new Object[initialCapacity];
stack = tempStack;
topIndex = -1;
initialized = true;
} // end constructor
// < Implementations of the stack operations go here. >
// < Implementations of the private methods go here; checkCapacity and
// checkInitialization are analogous to those in Chapter 2. >
// . . .
} // end ArrayStack
StackInterface.java
public interface StackInterface
{
/** Adds a new entry to the top of this stack.
@param newEntry An object to be added to the stack. */
public void push(T newEntry);
/** Removes and returns this stack\'s top entry.
@return The object at the top of the stack.
@throws EmptyStackException if the stack is empty before the operation. */
public T pop();
/** Retrieves this stack\'s top entry.
@return The object at the top of the stack.

public T peek();

The executive officers of Rouse Corporation have a performance-based c.docx
The executive officers of Rouse Corporation have a performance-based compensation plan. The performance criteria of this plan is linked to growth in earnings per share. When annual EPS growth is 12%, the Rouse executives earn 100% of the shares; if growth is 16%, they earn 125%. If EPS growth is lower than 8%, the executives receive no additional compensation.
In 2014, Joan Devers, the controller of Rouse, reviews year-end estimates of bad debt expense and warranty expense. She calculates the EPS growth at 15%. Kurt Adkins, a member of the executive group, remarks over lunch one day that the estimate of bad debt expense might be decreased, increasing EPS growth to 16.1%. Devers is not sure she should do this because she believes that the current estimate of bad debts is sound. On the other hand, she recognizes that a great deal of subjectivity is involved in the computation.
Questions
What is the ethical dilemma for Devers?
What are the alternative solutions? Evaluate whether the proposed solution is ethical.
Who are the stakeholders? How are they impacted?
Solution
What is the ethical dilemma for Devers.
Few executives ever see jail even though the results of unethical behavoir can greatly affect stakeholders.
The prevalence of major corporate scandals over the years has helped increase public awareness of two major ethics concepts -- stakeholders and ethical dilemmas. While these concepts are not unique to the study of business, they tend to be more commonly applied to ethical corporate decision making. For example, the corporate social responsibility movement is a direct application of these ideas in real life business practice. But what exactly do they mean?
Stakeholders
Stakeholders are broadly defined as anyone who is impacted by a decision-maker

The EU recently admitted the Eastern European countries- How do you as.docx
The EU recently admitted the Eastern European countries. How do you assess the impact of the EU\'s expansion? What are the costs and benefits of the expansion for the U.S. economy?
Solution
The accession of eight Central and Eastern
European countries (CEECs) to the European
Union in 2004 will bring some important bene-
fits. The new members will gain from reduced bar-
riers to trade and investment. By 2010, the move-
ment of labor will also be freed. But accession to
the EU is neither a necessary nor a sufficient con-
dition for economic growth. The combined effects
of market access and economic liberalization, not
EU membership, optimize economic growth.
Unfortunately, the incoming EU members had
to choose between the common market on the
one hand and economic liberty on the other.
Instead of concluding free-trade agreements with
the EU, the CEECs were cajoled into an increas-
ingly centralized superstate, in which most of
their comparative advantages will be legislated out
of existence. As a result, economic growth in
Central and Eastern Europe (CEE) will continue
to be suboptimal. The loss of potential future eco-
nomic growth will be only partly offset by the
CEEC

The energy levels of electrons are related to their- a) Position on t.docx
The energy levels of electrons are related to their:
a) Position on the Periodic table
b) Atomic mass units
c) Isobars
d) Shells
e) Isotopes
Solution
The energy levels of electrons are related to their:
d) Shells
An early model of the atom was developed in 1913 by the Danish scientist Niels Bohr (1885–1962). The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circular electron shells at specific distances from the nucleus, similar to planets orbiting around the sun. Each electron shell has a different energy level, with those shells closest to the nucleus being lower in energy than those farther from the nucleus. By convention, each shell is assigned a number and the symbol n

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
