codeforces segment tree

Hi 🙂 These are some segment tree problems on codeforces. Ofcourse it is not complete and I hope we will complete it with your help. And great thank to magar0_o for helping me. You can also find many Segment Tree problems on A2 Online Judge. They are ranked

A wonderful implementation of segment tree . Thanks for this awesome article. If you write another blog or add a section in this blog on persistent segment tree (non-recursive implementation) that will be very helpful. Thanks Again 🙂 @Al.Cash →

Thanks, the problem added to the list. When you are unfamiliar with the segment tree it’s better to solve the problem using the segment tree even if there is a better time-complexity because you will understand different usage of the segment tree. (At least that’s
