@[YONEX](/user/737219) 改用树状数组

@[__yun__](/user/749539) 可是想调一下这个分块

@[YONEX](/user/737219) 这题用分块会超时，如果你想打分块板子可以去线段树那边

@[添哥](/user/264463) okk,感谢

@[YONEX](/user/737219) 别急，这题我分块过了的

@[wjr_jok](/user/1236806) 求求，拜谢了 %%%

首先哥们你 `change_point` 里少了个 `sum[pos[a]]+=b`

还有 `sum` 要开 `ll`

@[wjr_jok](/user/1236806) 啊？这题 $5\times 10^5$ 你分块过了？
