Minimum Operations to Reduce X to Zero | O(N) Optimal | Leetcode #1658 

This video explains a very important programming interview problem which is to find the minimum number of operations to reduce a given number X to 0.I have already explained the dynamic programming solution for this problem in my previous video.Here, I have explained the optimal approach using hashmap.I have first solved the problem statement using proper examples and then i have shown the intuition for solving this problem. I have used easy examples and I have shown the algorithm using dry run.At the end, I have also shown the code walkthrough.CODE LINK is present below as usual.
