T2 随机数据

#include<cstdio>
#include<cstdlib>
#include<ctime>
#define random(x) rand()%x
using namespace std;
int main()
{
	srand(time(0));
	//freopen("data.in","w",stdout);
	printf("10 3 %d\n",random(10));
	for(int i=1;i<=10;i++)
	  printf("%d %d\n",random(3),random(10));
}

T2 60分暴力

#include<cstdio>
#include<cctype>
#define ll long long
using namespace std;
int read() {
	int x=0,f=1; char c=getchar();
	while(!isdigit(c)) {if(c=='-')f=-f;c=getchar();}
	while(isdigit(c)) x=(x<<1)+(x<<3)+c-48,c=getchar();
	return x*f;
}
void print(int x){
	if (x>9) print(x/10); putchar(x%10+48); return;
}
ll n,k,p,color[5000],cost[5000],ans;
int main()
{
	freopen("data.in","r",stdin);
	freopen("data.ans","w",stdout);
	n=read();k=read();p=read();
	for(ll i=1;i<=n;i++){
		color[i]=read();cost[i]=read();
	}
	for(int i=1;i<=n;i++)
	  for(int j=i+1;j<=n;j++){
	  	if(color[i]==color[j]){
	  		for(int k=i;k<=j;k++)
	  		  if(cost[k]<=p){
	  		  	ans++;
	  		  	break;
			  }
		  }
	  }
	print(ans);
}

T2 对拍

#include<windows.h>
#include<cstdio>
using namespace std;
int main()
{
	while(1){
		system("data.exe");
		system("BL.exe");
		system("T2.exe");
		if(!system("fc data.ans data.out"))
		  printf("AC\n");
		else
		{
			printf("WA\n");
			break;
