I've got Wrong Answer on this one. And I notice that there is only one person, who is problem setter of this problem, getting Accepted on this problem. So I doubt if there are some tricky/wrong test case.

My algorithm is binary search the answer(pre-determine if the answer is infinite) and use ...

After lots of REs I realize that there must be some extra empty lines in the input file!!!(There's nothing about this in the problem statement.) I changed my program and got Accepted.

The problem setter is very irresponsible because I've got Accepted after I submitted this code:

#include<stdio.h>
#include<assert.h>
char s[10000];
int main()
{
int i;
while(gets(s))
for(i=0; s[i]; i++)
assert(s[i]>='0' && s[i]<='9' || s[i]==' ');
return 0;
}


Maybe the site admin. should ...

I can't tell you how angry I am when I realize that the numerator and denominator in the problem can be very large(exceed long long in C/C++) after lots of TLEs & REs.

The problem setter should add this information in the problem statement I think.

Can anybody give me some test cases? I used long long to avoid integer overflow but I still have got 5 WAs.

Thanks in advance.
