CSP(noip)中的简单对拍写法

以a+b为例

这是随机数据

#include<iostream>
#include<cstdio>
#include<ctime>
using namespace std;
int main(){
    freopen("rand.txt","w",stdout);
    int a,b;
    srand(time(0));
    a=rand()%10+1;b=rand()%10+1;
    cout<<a+b;
}

这是正解(假设它是正解!)

#include<iostream>
#include<cstdio>
#include<ctime>
using namespace std;
int main(){
    freopen("rand.txt","r",stdin);
    freopen("1.txt","w",stdout);
    int a,b;
    cin>>a>>b;
    cout<<a+b;
}

这是暴力(假设它是暴力)

#include<iostream>
#include<cstdio>
#include<ctime>
using namespace std;
int main(){
    freopen("rand.txt","r",stdin);
    freopen("2.txt","w",stdout);
    int a,b;
    cin>>a>>b;
    cout<<a+b;
}

最后就是对拍了

#include<bits/stdc++.h>
using namespace std;
int main(){
    while(1){
        system("rand.exe");
        system("1.exe");
        system("2.exe");
        if(system("fc 1.txt 2.txt"));
        while(1);
    }
}
