Hi.
I find out that test #3 looks like this :
p = 3
V = 4
n = 0

When we need to find T, answer will be "undefined" if and only if n = 0 (because, in this way, we get division by zero).
In second and in third tests n=0, and we need to find T. I wrote code like this :

if( we need find T ) {
    if( n==0 )
         printf("undefined\n");
}


But, in this way, I get WA 3.
What is wrong? Please, check test, or, if I made mistake, help me figure it out.
Thanks.

the answer is "error" because there is no solution

But in this case I get WA 2, changing only one string in my code.
