I have been learning DP from basic since last couple of days and I thought of solving all DP tagged problems from basic by filtering into the problem set by tag and complexity. I tried this filter (https://mirror.codeforces.com/problemset?tags=dp,1-1000) and found few problems which I didn't find related to DP. Are these incorrectly tagged as DP problem or is there something which I'm missing in these problems?

If these are incorrectly tagged as DP then would request to correctly tag the problems as it helps newbie's like me to filter problems and practice concepts.

Any help would be much appreciated.

Thanks.
