How to learn Segment Tree?
By death_bringer, history, 2 years ago, In English

To get straight to the point. I know the basics and implementation of segment tree but I can't solve problems using it. Because I don't know its applications and advantages (Practical ones).

So can anyone have a list of problems going from easy to a medium level so that I can try to get my basics straight?

I kinda have the same problem for DSU. So, If anyone has list for that, please share it will be very helpful.
