C代码,超简单,为什么还wa。。。#include <stdio.h>
#include<string.h>
int main()
{
int T,i,j,q,maxl,N;
int arr[400][2];
int arr2[400][2];
while(scanf("%d",&N)!=EOF)
{
while(N--)
{
scanf("%d",&T);
memset(arr2,0,sizeof(arr2));
for(i=0;i<T;i++)
for(j=0;j<2;j++)
scanf("%d",&arr[i][j]);
for(i=0;i<T;i++)
for(j=0;j<2;j++)
for(q=0;q<T;q++)
if(arr[i][j]>arr[q][0]&&arr[i][j]<arr[q][1])
arr2[i][j]++;
for(maxl=0,i=0;i<T;i++)
for(j=0;j<2;j++)
if(maxl<arr2[i][j])maxl=arr2[i][j];
printf("%d\n",(maxl+1)*10);
}
}
return 0;
}
