What is a stack and how it works? What is an Abstract data type and how it’s related with the stack? In this post we’ll explore the stack data structure, I’ll go through the theory behind, explain why stacks are important programming tools, create a custom implementation of a stack with an array from scratch and finally, go through some interesting examples. By the end of this post I do hope that you’ll have a very good understanding of how a stack works under the hood and how you can use it to tackle day-to-day programming problems.
