Description

A stack is a linear data structure that follows the Last In, First Out (LIFO) principle, meaning that the most recently added element is the first one to be removed. It operates with two main operations: push, which adds an element to the top of the stack, and pop, which removes the element from the top. Additionally, a peek or top operation allows viewing the element at the top without removing it. Stacks are commonly used in algorithms for parsing expressions, function calls (call stack), undo mechanisms, and managing recursive processes.
