LeetCode - solved 200 medium level problems

Progress report #2: I solved 100 medium level problems of LeetCode on 3/8, next 50 on 4/15, and today finished 200th. 56 days for the last 50 problems. Slightly less than one problem per day. Worse than the previous 50, but this time the problems were harder (lower acceptance rate). Anyway I now have strong confidence of being able to solve most of easy to intermediate level coding problems on major computer science algorithms. One weak area though is Dynamic Programming, particularly on sub-sequences (subset of array, where you can pick any elements but maintaining the original order). Now that I hit a significant milestone of 200, I plan to switch gear to self-studying DP, using GeeksForGeeks list of hundreds of representative problems. But I will also keep solving medium level LeetCode problems.
