太区区

首先需要写一个自己认为对的和一个暴力

然后您需要一个数据生成器

代码在下面:

#include<cstdio>
#include<ctime>
#include<cstdlib>
#include<algorithm>
#define ll long long
using namespace std;
int random(int n){
	return (ll)rand() * rand() % n;
}
int main(){
	int a[10001]; 
	srand((unsigned)time(0));
	int n=random(100000)+1;//随机生成<=1e5个绝对值在1e9以内的整数
	int m=1000000000;
	for(int i=1;i<=n;i++)
	{
	a[i]=random(2 * m + 1) - m ;
	printf("%d ",&a[i]); 
	} 
//可以再random_shuffle一下
//	srand((unsigned)time(NULL));
//	for(int i=1;i<=100;i++)
//	{
//	int a= random(99435323)+rand();
//	int b= random(20040712)+rand();
//	printf("%d %d ",&a,&b); } 
}

然后需要写一个对拍程序

#include<cstdio>
#include<windows.h>
#include<ctime>
using namespace std;
int main(){
    int t=100;
    for(int i=1;i<=t;i++){
        system("data>a+b.txt");
        system("force<a+b.txt>force.txt");
        double t1 = clock();
        system("force2<a+b.txt>force2.txt");
        double t2 = clock();
        if(system("fc force.txt force2.txt")) {
        	puts("WRONG");
        	return 0;
    }
    else printf("%d time %lf ",i,t2 - t1);
	}
    return 0;
}

记住要自己开两个exe文件和txt文件

好了,然后就可以愉快的爆零了

@echo off
:go
data.py > in.txt
1.exe < in.txt > out.txt
std.exe < in.txt > ans.txt
fc out.txt ans.txt
if not errorlevel 1 goto go
pause
