Thanks again!!

Hi!. I'm also looking for hints for this problem. I think my program gives a right answer. I've tried with 0 size... but still got WA

Thanks in advance!.

You should complete with blanks your lines till the end. I mean... all the lines must have the same width, and your fifth line:

*******aaa***aaa***aaa***aaa***aaa

is not completed:

*******aaa***aaa***aaa***aaa***aaa******

I still got WA!!!

Hi!. I've dealed with ASCII code, blanks, zero size, eight digits numbers... but I always get WA. Does anyone know about the critical input??.

Hi there!. This is my code:

#include <stdio.h>

long double Factorial(int f, int s) {
if (f < s) return 1;
else return f*Factorial(f-1, s);
}

main() {
long double n, k;
while ((scanf("%Lf %Lf\n", &n, &k)>0)&&(n>0))
if (k > 0)
printf("%.0Lf\n", Factorial(n, n-k+1)/Factorial(k, 1));
else ...
