拍

没事看一眼

#include<bits/stdc++.h>
using namespace std;
signed main(){
    int s,t;
    for(int cnt=0;cnt<=1e4;cnt++){
    	s=clock();
        system("data.exe>data.in");
        system("2.exe<data.in>2.out");
        t=clock();
        system("1.exe<data.in>1.out");
        if(system("fc 1.out 2.out"))system("pause>nul");
        else cout<<"AC : "<<t-s<<'\n';
    }
    return 0;
} 

顺便加一段输出内存占用(如果出来是\(0\)就 \(lld\) 和 \(lf\) 换着试试)

#define _DEG
char _b;
//..../
char _c;
signed main(){
    #ifdef _DEG
        printf("%lld mb",(&_c-&_b)/1048576);
    #endif
    return 0;
}
