提供hack和对拍程序

// 造数据
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <algorithm>
#define int long long
using namespace std;
int rand(int l,int r){
	return rand()%(r-l+1)+l;
}
int a[10010];
signed main()
{
	srand(time(0));
	
	int t;
	scanf("%lld",&t),t*=rand(),t%=100;
	while(t-->0)
		rand();
	
	int n = 5,x = 100;
	for(int i=1;i<=n;i++)
		a[i] = rand(-x,x);
	sort(a+1,a+n+1);
	
	int tot = 0;
	for(int i=1;i<=n;i++)
		if( i != n && a[i] == a[i+1] )
			a[i] = x+1,tot++;
	
	printf("%lld\n",n-tot);
	for(int i=1;i<=n;i++)
		if( a[i] != x+1 )
			printf("%lld %lld\n",a[i],rand(0,x*2));
	
	return 0;
}

// 对拍
#include <iostream>
#include <stdio.h>
#include <windows.h>
using namespace std;
long long k;
int main()
{
	while(true)
	{
      // ans1.txt文件需要提前创建
		system("build.exe < ans1.txt > in.txt");
		
		system("你的程序.exe < in.txt > ans1.txt");
		
		system("标程.exe < in.txt > ans2.txt");
		
		printf("[%lld] ",++k);
		if( system("fc ans1.txt ans2.txt") )
			break;
	}
	return 0;
}
