Leetcode daily challenge 3-June-2022 in-depth explanation in English

The video contains the solution to problem 304 on leetcode. I have also added the problem statement link so that you can try the problem by yourself. The question is based on the prefix sum. I have tried to explain things in-depth and how we reach to optimized solution from the naive one with a detailed analysis of the approach. If you have any doubts then you can mention them in the comments and I will try to resolve that.
