Introduction and Background
In recent lectures we discussed using arrays, classes and interfaces (see newly added course
notes if you want to read ahead about interfaces – we will cover them this week in lecture). In
this lab you will utilize all of these topics to build a simple yet useful new class. Consider the
following interface describing the methods for a simple double ended queue (or deque):
public interface SimpleDeque
{
public void addFront(Object X); // Add Object X at front of list
public void addRear(Object X); // Add Object X at rear of list
// If array is full, add methods should do nothing
public Object removeFront(); // Remove and return Object X from
// front of list
public Object removeRear(); // Remove and return Object X from
// rear of list
// If array is empty, remove methods should return null
public boolean isEmpty(); // Return true if the list is empty
// Return false otherwise
}
A queue has the behavior such that items are added at the rear and removed from the front,
thereby giving a First In First Out (FIFO) access to the items added and subsequently removed
from the list. No other manipulations of the data are permitted (for example, we cannot add or
remove anywhere in the middle). Looking at it \"in reverse\", we could add new items at the
front of the queue and remove them from the rear. This is still providing FIFO access, but just
from a different point of view. Now consider both adding and removing items at the rear of the
list (without ever accessing the front). This is called stack access and gives us Last In First Out
(LIFO) access to the items (the data is removed in reverse order). The same behavior occurs if
we both add and remove at the front without ever accessing the rear of the list.
The simple deque above is expressed as an interface rather than a class, because we are not
describing the data or how it is represented -- we are simply describing its access behavior.
However, to actually build a working deque, we need a class that implements the interface
above. For example:
public class MyDeque implements SimpleDeque
{
Object [] theData;
int numItems;
public MyDeque(int maxItems)
{
theData = new Object[maxItems];
numItems = 0;
}
// Implementation of the five methods of SimpleDeque, plus
// perhaps other methods as well
}
Note that the implementation above uses an array of Object to store the items in the deque. Since
Object is the base class to all other Java classes, an array of Object can thus be used to store any
Java class types (we can even store primitive values if we utilize their wrapper classes). Also
note that nothing in the SimpleDeque interface requires an array to be used to store the data. You
will see in your CS 0445 course that a linked list may in fact be a better implementation than an
array in this case. However, for this implementation we will use an array because it is simple and
easy to understand.
Another important thing to notice about the partial implementation above is tha.
Assg 14 C++ Standard Template Library (STL)(Extra Credit .docxfestockton
Assg 14: C++ Standard Template Library (STL)
(Extra Credit Opportunity)
COSC 2336 Fall 2019
Dates:
Due: Sunday December 08, by Midnight
Objectives
ˆ Practice using an enterprise level set of data structures and algorithms
provided by the STL.
ˆ Connect what we learned about things like stacks, queues, lists, dictio-
naries, etc. to their implementations and applications from the C++
STL.
Description
This assignment is a bit di�erent than the previous assignments in the class,
and is being given as an extra credit opportunity. The assignment is open
ended. I have described 7 tasks or items you can perform, involving the
C++ standard template library. I will give up to 5 points for each of the 7
tasks (for a total of up to 35 points), that will be considered extra credit,
and applied to your programming assignment portion of the course grade to
make up some points on past programs in the class.
This assignment is open ended. I have not given you any starting code or
tests/assertions to use for the assignment. To get credit for the assignment,
you should submit a single �le named "assg14-stl.cpp". The �le should be
compilable and runnable using the C++ IDE/compiler environment you and
I have been using this semester for the class assignments. I would prefer that
you create a separate function for each of the tasks you chose to submit work
for, and that your main function simply calls each of the functions for the
1
task. Your functions should be documented and code formatted using the
usual class style guidelines. You can make up some work for the functions
to do, e.g. to pass them in a parameter and return a value, if you wish.
However, it is also su�cient to simply have void functions that take no
parameters. You should, though, add some output and test assertions of
your own to demonstrate your code working on the tasks using the STL
containers and algorithms. Also if you do more than 1 task demonstrating
a container, make sure you always use a di�erent type to be stored in the
container. For example, don't demonstrate all of your containers on <int>
values, use a variety like <double> <string> <char>, or even better, create
your own small structure or class and demonstrate a container of those user
de�ned types you created.
You should use our textbook for reference on using the STL containers
and algorithms. Another good online reference for the C++ STL is:
cplusplus.com: http://www.cplusplus.com/reference/stl/
You may work on any of the following tasks for this extra credit oppor-
tunity:
1. The STL divides up its containers into 4 categories. The simplest are
the sequence containers, which are intended to store data and access
it in a sequential manner. Vectors are like basic arrays in C, but they
are dynamic and have the ability to resize themselves automatically
when an element is inserted or deleted. Vectors really use C arrays
for their implementation. Insertion can be done in O(1) time to the
end, though if the vecto ...
Akka Streams - An Adobe data-intensive storyBianca Teşilă
A case study by Adobe's Real-Time Customer Data Platform on how we've embraced Akka Streams to deliver personalised experiences at a rate of 1 Million events per second. Our systems enable customers to seamlessly activate their data for cross-channel marketing campaigns, email campaigns, targeted advertising, and many other use cases in realtime.
While this might seem a rather simple function, there are a few important criteria we've had to consider:
- Back-pressure: Carefully consume the data without overwhelming our systems — or those of our partners.
- Resilience: Ensure that the failure of one integration does not affect neighboring integrations.
- Asynchrony: Use computing resources efficiently and maintain the level of performance our customers expect.
During this talk, we will outline how we've been leveraging Akka Streams' capabilities and the key points that aided us through our journey, which may also prove useful to developers on similar projects. And because we want to offer a real practical view of our lessons, we will be walking you through a step by step performance tuning exercise we performed for one of our components -- a story that began looking rather impossible to reach our target, but happily ended with a 10x improvement.
3. QUEUES
instance of an abstract data type (ADT) that
formalizes the concept of restricted collection
(FIFO = first in first out)
4. QUEUES: BASIC OPERATIONS
enqueue(x)
dequeue()
Removes the element from the head of the queue and
returns it
Returns an error if the stack is empty
peek()
Adds the element x at the tail of the queue
Returns (but does not remove) the element at the head of
the queue
isEmpty()
Returns 1 if the queue is empty and 0 otherwise
5. QUEUES: IMPLEMENTATION
with a static data structure (array, circular
array)
with a dynamic data structure (list)
‼Short reminder:
Why do we use circular arrays instead of simple arrays?
8. QUEUES VS STACKS
‼Exercise:
Implement a stack using 2 queues. The corresponding class is
QueuedStack and has the following methods:
an empty constructor
destructor
push
pop
There are several solutions for this task.
Using a similar approach, implement a queue using 2 stacks:
StackedQueue.
9. QUEUES AND STACKS: APPLICATIONS
‼Exercise:
Implement a stack which provides an efficient get minimum
function along with regular push and pop functionality.
Hint: use an auxiliary stack.
Taking into consideration that a queue can be implemented
using 2 stacks, use a similar approach for getting the
minimum element out of a queue.
10. HOMEWORK
o
Finish all the lab exercises.
o
Implement a messaging system using queues.
Messages are received in the order they are sent
You should use the following classes:
Message
MessageSender
MessageReceiver
A Message object has a sender, recipient, content (make an array
of chars!!) and a date
A Message is placed in a queue by a MessageSender object
A Message is removed from a queue by a MessageReceiver object,
which can also display the content of the message.
Your queue class can receive any types of objects, including
Message Objects
