测了许多数据都行啊 咋还不过那#include<iostream>
#include<string.h>
#include<math.h>
using namespace std;
int main()
{
char a[9];
int n=0,l=0,sum=0,k=0;
cin>>n;
for(int i=0;i<n;i++)
{
cin>>a;
l=strlen(a);
if((a[1]-'0')<4)k=a[0]-'0';
if((a[1]-'0')>4)k=(a[0]-'0')+1;
if(a[1]-'0'==4)
{
if(l==2)k=a[0]-'0';
for(int m=2;m<l;m++)
{
if((a[m]-'0')!=0)
{
k=a[0]-'0'+1;
break;
}
else
k=a[0]-'0';
}
}
sum=k*pow(10.0,l-1);
cout<<sum<<endl;
sum=0;
}
return 0;
}
