Hi .. so i've been solving this problem [problem](https://codeforces.com/edu/course/2/lesson/5/2/practice/contest/279653/problem/D) but it's still gives me a WA can someone please tell me what's wrong with my code [Code](https://pastebin.com/VeB3RBMaG3q9EVEy)? (my code is readeable so it won't be hard for someone who know segment tree to find an error). The WA is in the sample test.↵
