What is Stack Data Structure?

A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. It behaves like a stack of plates, where the last plate added is the first one to be removed....

Key Operations on Stack Data Structures

Push: Adds an element to the top of the stack. Pop: Removes the top element from the stack. Peek: Returns the top element without removing it. IsEmpty: Checks if the stack is empty. IsFull: Checks if the stack is full (in case of fixed-size arrays)....
