I need some help about what exactly should I do for inoi

My prob is i am confused about which dp topics to do and which to not. For example dp with bit masking is required or not. Also there were many many topics on geeks for geeks and i couldnt get which ones to do as time is limited. It is nowhere mentioned on iarcs etc. Which questions of dp go beyond inoi level? Also is there a need to do segment trees ( i have no idea about it).
