对拍 .cpp 参考

#include <bits/stdc++.h>
using namespace std;

int main() {
    while (true) {
        system("data.exe > test.txt");
        system("right.exe < test.txt > right_ans.txt");
        system("test.exe < test.txt > test_ans.txt");
        if (system("fc right_ans.txt test_ans.txt")) {
            break;
        }
    }

    return 0;
}
