@torus711 Ohh That's nice!!

@Vid__26 Yes. Fenwick Tree is also called Binary Indexed Tree. It processes following queries for array: 1. Add v for index i 2. Summate of range [ l, r ) 3. Get minimum i for v s.t. v <= sum of [ 0, i ) D is solved by 1 and 3. And I didn't implement the tree since I've created a snippet

AtCoder おつでし やったこと　A: 言われた通りに．drop と dropEnd B: 添字全部回して，上下左右の外郭に含まれる回数を 4 から引く C: 各 'C' について右・左に伸ばせる長さの min の和 D: クエリ先読み + 座標圧縮して Fenwick Tree に載せる
