Can somebody provide a list of problems sorted by difficulty level on the topics Graph (like bfs,dfs etc) and DP which are on Codechef. I have already solved some classical problems on SPOJ and now I want some questions of medium difficulty level. TIA.
For Codeforces you can check these 2 links:
Tip: you can use green tick in the corner to sort by successful submission. it is a good measure of difficulty.
Try the tag feature at the homepage. That should suffice.
Ohh didn’t see it. Thanks a lot.
