@[Fraciton](/space/show?uid=32107) 你的快读是假的。我帮你改了一下(~~未实测AC~~) ```cpp template <typename T> il void read(T &dig) { char c = getchar(); bool flag = false; dig = 0; while(!isdigit(c) && c != '-') c = getchar(); if(c == '-') flag = true, c = getchar(); while(isdigit(c)) dig = dig * 10 + c - '0', c = getchar(); if(flag) dig = -dig; //就是这!!! } ```
