• 针对WA \(\longrightarrow\) 对拍！！！

例：造数据

#include <cstdio>
#include <cstdlib>
#include <ctime>
#include <cstring>
#include <iostream>

using namespace std;

int main()
{
    srand(time(0));
    freopen("xxx.in", "w", stdout);

    int n = rand() % 1000 + 1;
    int m = rand() % 1000 + 1;
    int up = 1000;

    cout << n << ' ' << m << '\n';

    for (int i = 1; i <= n; ++i)
    {
        for (int j = 1; j <= m; ++j)
        {
            cout << rand() % up + 1 << ' ';
        }
        cout << '\n';
    }
    return 0;
}

比较：

#include <cstdio>
#include <cstdlib>
#include <ctime>
#include <cstring>
#include <iostream>

using namespace std;

int main()
{
    while(1)
    {
      system("xxx.exe");//运行造数据的文件
      system("xxx1.exe");//运行要交的代码
      system("xxx2.exe");//运行暴力
      if (system("fc xxx1.out xxx2.out")) break;//比较两个文件的结果
    }
   return 0;
}
