Damn, you are green and solving segment tree...
If you know russian you can watch pashka's tutorial on that problem, and find mistake by yourself
first i don't although no need bcs tutorial is in english and secondly it will be no help he uses recursive segment tree while i use iterative one.
Iterative segment tree?
Wow that pretty interesting, my bad
anyways if you will help me do it else stop wasting my time
I wanted to, but I'm doing recursive and you're doing iterative
no need to be that toxic, he is just asking it, you are responding like you are cm or expert, but you cannot solve basic questions.
