Problem:
How Many Divisors?

Write a program which reads three integers a, b and c, and prints the number of divisors of c between a and b.

Input

Three integers a, b and c are given in a line separated by a single space.

Output

Print the number of divisors in a line.

Constraints

1 ≤ a, b, c ≤ 10000

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main(){

 int i, a, b, c, d, e, mod;

 scanf("%d%d%d", &a, &b, &c);

 d = a;

  for(i = d; i = b; i++){

   mod = c % a;

   a++;
 
   if(mod == 0){
   e++;
   }

  }

 printf("%d\n", e);

}
