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]);

Finally, identify the line that matches what you concluded above.
Deliverables:

completed this code to fulfill the requirement below:
Write a function to insert an integer into a singly-linked list of elements arranged from largest to
smallest. Requires that elements remain ordered after insertion.
2. The design of array-based stack
below is a picture of the function that needs to be used
below is the code of the above picture:
#include <string.h>
#.
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.
PR
IF 4
IF 5
IF 6
IR 7

The output for the input file shown above is :

public class dequeNode
This class will implement the linked nodes that will be used to implement the deque itself.
It should have the following protected data members.
protected dequeNode next; // next pointer to next node
protected dequeNode prev; // previous pointer to previous node
protected int val; // the integer value stored within the dequeNod.

Recursion to iteration automation.
A class that automates conversion from a C++ recursive function to an iterative function. It allow the recursive function to preserve its structure by reproducing the "call stack" on an std::stack. The examples use combinatorics to illustrate usage.
Implement the sequence class from Section 3.2 of the textbook. The d.pdf
Implement the sequence class from Section 3.2 of the textbook. The documentation and
definition portion of this sequence ADT is provided in textbook (pp.124-133), and is posted in
BlackBoard of this class too.
Also implement two operators + and += for the ADT. For the + operator, x+y (a new sequence)
contains all the items of x, followed by all the items of Y.
The statement x += y appends all of the items of y to the end of what’s already in X.
For simplicity, let’s assume the sequence contains integer items and the capacity is 30.
Write a simple application to manage a playlist of your favorite music, where the sequence class
is used to insert, delete, search and print the title of music.
Your application should read in integral numbers (an ID, instead of title, for simplicity) of each
piece of music and insert them onto a sequence. It should be able to insert an item at a specified
location, find and display the music currently at play, delete a specified item from the sequence
as well as display the entire list of music in the sequence.
// FILE: sequence1.h
// CLASS PROVIDED: sequence (part of the namespace main_savitch_3)
// There is no implementation file provided for this class since it is
// an exercise from Section 3.2 of \"Data Structures and Other Objects Using C++\"
//
// TYPEDEFS and MEMBER CONSTANTS for the sequence class:
// typedef ____ value_type
// sequence::value_type is the data type of the items in the sequence. It
// may be any of the C++ built-in types (int, char, etc.), or a class with a
// default constructor, an assignment operator, and a copy constructor.
//
// typedef ____ size_type
// sequence::size_type is the data type of any variable that keeps track of
// how many items are in a sequence.
//
// static const size_type CAPACITY = _____
// sequence::CAPACITY is the maximum number of items that a sequence can hold.
//
// CONSTRUCTOR for the sequence class:
// sequence( )
// Postcondition: The sequence has been initialized as an empty sequence.
//
// MODIFICATION MEMBER FUNCTIONS for the sequence class:
// void start( )
// Postcondition: The first item on the sequence becomes the current item
// (but if the sequence is empty, then there is no current item).
//
// void advance( )
// Precondition: is_item returns true.
// Postcondition: If the current item was already the last item in the
// sequence, then there is no longer any current item. Otherwise, the new
// current item is the item immediately after the original current item.
//
// void insert(const value_type& entry)
// Precondition: size( ) < CAPACITY.
// Postcondition: A new copy of entry has been inserted in the sequence
// before the current item. If there was no current item, then the new entry
// has been inserted at the front of the sequence. In either case, the newly
// inserted item is now the current item of the sequence.
//
// void attach(const value_type& entry)
// Precondition: size( ) < CAPACITY.
// Postcondition: A new copy of entry has been ins.

Queues
In computer science, a queue (/ˈkjuː/ kyew) is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position, known as enqueue, and removal of entities from the front terminal position, known as dequeue. This makes the queue a First-In-First-Out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed. This is equivalent to the requirement that once a new element is added, all elements that were added before have to be removed before the new element can be removed. Often a peek or front operation is also entered, returning the value of the front element without dequeuing it. A queue is an example of a linear data structure, or more abstractly a sequential collection.

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.
PR
IF 4
IF 5
IF 6
IR 7

The output for the input file shown above is :

7
----- Rear -----
----- Front -----

----- Rear -----

public class dequeNode
This class will implement the linked nodes that will be used to implement the deque itself.
It should have the following protected data members.
protected dequeNode next; // next pointer to next node
protected dequeNode prev; // previous pointer to previous node
protected int val; // the integer value stored within the dequeNod.

example algorithm the find(): find (Inputiterator first, Inputiterator last, const T& val) The find uses
two iterators for the bounds of the search, first and last. The 3rd parameter is the value being
searched for. if we look inside the find() we might see code like this (ref cplusplus.com): The

Recursion to iteration automation.
A class that automates conversion from a C++ recursive function to an iterative function. It allow the recursive function to preserve its structure by reproducing the "call stack" on an std::stack. The examples use combinatorics to illustrate usage.
Implement the sequence class from Section 3.2 of the textbook. The d.pdf
Implement the sequence class from Section 3.2 of the textbook. The documentation and
definition portion of this sequence ADT is provided in textbook (pp.124-133), and is posted in
BlackBoard of this class too.
Also implement two operators + and += for the ADT. For the + operator, x+y (a new sequence)
contains all the items of x, followed by all the items of Y.
The statement x += y appends all of the items of y to the end of what’s already in X.
For simplicity, let’s assume the sequence contains integer items and the capacity is 30.
Write a simple application to manage a playlist of your favorite music, where the sequence class
is used to insert, delete, search and print the title of music.
Your application should read in integral numbers (an ID, instead of title, for simplicity) of each
piece of music and insert them onto a sequence. It should be able to insert an item at a specified
location, find and display the music currently at play, delete a specified item from the sequence
as well as display the entire list of music in the sequence.
// FILE: sequence1.h
// CLASS PROVIDED: sequence (part of the namespace main_savitch_3)
// There is no implementation file provided for this class since it is
// an exercise from Section 3.2 of \"Data Structures and Other Objects Using C++\"
//
// TYPEDEFS and MEMBER CONSTANTS for the sequence class:
// typedef ____ value_type
// sequence::value_type is the data type of the items in the sequence. It
// may be any of the C++ built-in types (int, char, etc.), or a class with a
// default constructor, an assignment operator, and a copy constructor.
//
// typedef ____ size_type
// sequence::size_type is the data type of any variable that keeps track of
// how many items are in a sequence.
//
// static const size_type CAPACITY = _____
// sequence::CAPACITY is the maximum number of items that a sequence can hold.
//
// CONSTRUCTOR for the sequence class:
// sequence( )
// Postcondition: The sequence has been initialized as an empty sequence.
//
// MODIFICATION MEMBER FUNCTIONS for the sequence class:
// void start( )
// Postcondition: The first item on the sequence becomes the current item
// (but if the sequence is empty, then there is no current item).
//
// void advance( )
// Precondition: is_item returns true.
// Postcondition: If the current item was already the last item in the
// sequence, then there is no longer any current item. Otherwise, the new
// current item is the item immediately after the original current item.
//
// void insert(const value_type& entry)
// Precondition: size( ) < CAPACITY.
// Postcondition: A new copy of entry has been inserted in the sequence
// before the current item. If there was no current item, then the new entry
// has been inserted at the front of the sequence. In either case, the newly
// inserted item is now the current item of the sequence.
//
// void attach(const value_type& entry)
// Precondition: size( ) < CAPACITY.
// Postcondition: A new copy of entry has been ins.

Queues
In computer science, a queue (/ˈkjuː/ kyew) is a particular kind of abstract data type or collection in which the entities in the collection are kept in order and the principal (or only) operations on the collection are the addition of entities to the rear terminal position, known as enqueue, and removal of entities from the front terminal position, known as dequeue. This makes the queue a First-In-First-Out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed. This is equivalent to the requirement that once a new element is added, all elements that were added before have to be removed before the new element can be removed. Often a peek or front operation is also entered, returning the value of the front element without dequeuing it. A queue is an example of a linear data structure, or more abstractly a sequential collection.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...

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.

Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
