一组数组没过，帮看看#include<iostream>
using namespace std;
int main()
{
int ncase,i,max,j,n,loop[410],a,b,temp;
cin>>ncase;
while(ncase--)
{
cin>>n;
max=0;
memset(loop,0,sizeof(loop));
for(i=0;i<410;i++)
loop[i]=0;
for(i=0;i<n;i++)
{
cin>>a>>b;
if(a>b)
{
temp=a;
a=b;
b=temp;
}
for(j=a;j<=b;j++)
{
loop[j]++;
if(loop[j]>=max)
{
max=loop[j];
}
}
}
cout<<max*10<<endl;
}
return 0;
}
//未通过的测试数据，官方答案是20，我怎么觉得是10
/*
10
2 3
4 5
6 7
8 9
10 11
12 13
14 15
16 17
18 19
20 21
