Hi, if you compare [this submission (296ms)](https://codeforces.me/contest/1625/submission/247553687)↵
with [this one (3025ms)](https://codeforces.me/contest/1625/submission/247553671), this is the difference:↵

I think this is crazy because `g` is a `vector<vector<int>>` with size `3 * 10^5` with at most `3 * 10^5` entries, and the function `build` that returns `g` is called once in the program. ↵
This huge time difference is the same on both 64-bit C++ compilers, but it is not present in the 32-bit C++ compiler.
