Stack

Explore the stack data structure in Go, understanding its last-in-first-out operation and key methods such as push, pop, and top. Learn practical applications including recursion, postfix evaluation, and depth-first search.

Introduction

The stack is a data structure that operates on the last-in-first-out (LIFO) principle. This means that the elements that we inserted last would be removed first.

Applications of stacks

The stack is used in a wide variety of applications, including:

  • Implementation of recursive calls.
  • Postfix evaluation of an expression.
  • Backtracking.
