This is the 69th Video on our Dynamic Programming (DP) Playlist.
In this video we will try to solve a very good DP Problem - Painting the Walls (Leetcode-2742).
I will be explaining the recursion+memo approach in this video. We will also see why Greedy Fails for this problem.
A separate video will come for Bottom Up of this video.
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
