Hi Ayushi, thank you for the video. I have been following most of your lectures, you are explaining very well. Can you please make a video for Leetcode 308: Range Sum Query 2D - Mutable (the current question continuation problem.). I have worked the same method, I also tried doing prefix sum over matrix but time complexity is more. Looking forward to a solution for this problem

[@AyushiSharmaDSA]
