新建cpp时直接复制就可以了
#include <bits/stdc++.h>
#define LL long long
using namespace std;
namespace GZY {
inline int getint() {
int x = 0; char c = getchar(); bool f = 1;
while (!isdigit(c)) { if (c == '-') f = 0; c = getchar(); }
while (isdigit(c)) { x = (x*10) + (c-'0'); c = getchar(); }
return f ? x : -x;
}
void main() {
}
}
int main() {
GZY::main();
return 0;
}
