(JAVA) Why do we need a dynamic stack? How do you implement a dynamic stack array?

Expert Solution

The stack is a linear data structure that is used to stores the collection of objects and it follows LIFO. But if you want to store more data you can use the dynamic stack, it is a stack data structure whose length and capacity (max no. of elements can be stored) increases /decreases in real-time based on operations like insertion, deletion,..etc performed on it.

A stack can be implemented by an array but since we are using an array to implement we cannot insert elements more than the size of the array, if we do it'll throw an error "memory overflow" because the size of the array is fixed and that's a problem there. To overcome this problem we use stack dynamic.

To make a stack dynamic we implement stack using LinkedList such stack is called dynamic stack.

How to implement dynamic stack array?

Implementation of dynamic stack:

Save this as Stack.java

Now save this as DynamicStackTest.java

To compile the program:

javac -d .Stack.java

javac -d .DynamicStackTest.java

and to run:

java ClassIllustration.DynamicStackTest

in C++ For this program, you are going to implement a stack using an array and dynamic memory allocation. A stack is a special type of data structure that takes in values (in our case integers) one at a time and processes them in a special order. Specifically, a stack is what's called a first-in-last-out (FILO) data structure. That is to say, the first integer inserted into the stack is the last value to be processed. The last value in...

For this assignment you will implement a dynamic array. You are to build a class called MyDynamicArray. Your dynamic array class should manage the storage of an array that can grow and shrink. The public methods of your class should be the following: MyDynamicArray(); Default Constructor. The array should be of size 2. MyDynamicArray(int s); For this constructor the array should be of size s. ~MyDynamicArray(); Destructor for the class. int& operator[](int i); Traditional [] operator. Should print a message...

0. Introduction. In this assignment you will implement a stack as a Java class, using a linked list of nodes. Unlike the stack discussed in the lectures, however, your stack will be designed to efficiently handle repeated pushes of the same element. This shows that there are often many different ways to design the same data structure, and that a data structure should be designed for an anticipated pattern of use. 1. Theory. The most obvious way to represent a...

Implement a class Polynomial that uses a dynamic array of doubles to store the coefficients for a polynomial. Much of this work can be modelled on the C++ dynamic array of ints List that we discussed in class. This class does not need the method the overloaded += operator. Your class should have the following methods: Write one constructor that takes an integer n for the degree of a term and a double coefficient c for the coefficient of the...
