Equal Stacks is a programming challenge on HackerRank that uses the stack data structure. You need to balance out 3 stacks such that they have the maximum height. Watch the video to understand the problem in a simplified manner. I then work along with you to solve it first using a Brute Force approach, and then an efficient approach. All along with visuals and explanations.
