Notes: The judge file contains invalid first line denoting the number of test cases. You should skip any nondigital characters in the very beggining of it. Here is the code example in C:

char buf[1024];
scanf( "%s", buf);
char *s = buf;
while( *s != '\0' && (*s < '0' || *s > '9') ) s++;
int t;
sscanf( s, "%d", &t);
while( t-- > 0 )
{
...
}

Also you should print "\r\n" instead of "\n" in the end of any output string to avoid PE.
