Question

what is Stacks

Answer 1

A stack is a data structure that follows the Last In, First Out (LIFO) principle, where the last element added to the stack is the first to be removed. It has two main operations: pushing (adding) an element onto the stack and popping (removing) an element from the top of the stack. Stacks are commonly used in programming for tasks such as function calls, expression evaluation, and backtracking algorithms.

Answer 2

Stacks are a type of data structure in programming that follows the Last In, First Out (LIFO) principle. This means that the last element added to the stack is the first one to be removed. Think of it like a stack of plates - you can only remove the top plate before accessing the ones below. Stacks are commonly used in algorithms for tasks such as function calls, backtracking, and expression evaluation.
