How push and pop operation is implemented in stacks?

In computer science, a stack is an abstract data type that serves as a collection of elements, with two main principal operations: Push, which adds an element to the collection, and. Pop, which removes the most recently added element that was not yet removed.

Can we implement two stacks single array?

To implement two stacks in one array, there can be two methods. First is to divide the array in to two equal parts and then give one half two each stack. But this method wastes space. So a better way is to let the two stacks to push elements by comparing tops of each other, and not up to one half of the array.

How will you partition the memory if two stacks implemented within a single array?

A simple solution would be to divide the array into two halves and allocate each half to implement two stacks. In other words, for an array A of size n , the solution would allocate A[0, n/2] memory for the first stack and A[n/2+1, n-1] memory for the second stack.

Can two push operation to insert new data items in the given stack are possible?

push() function is used to insert new elements into the Stack and pop() function is used to remove an element from the stack. Both insertion and removal are allowed at only one end of Stack called Top.

How do you implement a stack in CPP?

C++ Program to Implement Stack using array

1. Push – This adds a data value to the top of the stack.
2. Pop – This removes the data value on top of the stack.
3. Peek – This returns the top data value of the stack.

What happens when you pop from an empty stack while implementing using the stack ADT in Java * 1 point?

What happens when you pop from an empty stack while implementing using the Stack ADT in Java? Explanation: Every element from the given array ‘a’ is pushed into the stack, and then the elements are popped out into the array ‘b’. Stack is a LIFO structure, this results in reversing the given array.

What are the applications in which stack can be implemented?

Stack is used to evaluate prefix, postfix and infix expressions. An expression can be represented in prefix, postfix or infix notation. Stack can be used to convert one form of expression to another.

What is stack pop ()?

Stack. pop() method in Java is used to pop an element from the stack. The element is popped from the top of the stack and is removed from the same. Syntax: STACK.pop()
