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);
}
