1.Introduction

The stack is a fundamental abstract data structure for computer science that serves a collection of elements with the LIFO method and two main operations:

push (add a new element to stack)

pop (remove the top element)

Stacks are used mainly by algorithms(Backtracking,depth-first search,…), OS(operational systems), programming languages(memory management, call stack,… ), frameworks and many more applications.
