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(void){


int a,b,c,x;


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


int i;


for(i = a; a <= b; i++){


if(c % i == 0){


x++;


}


}


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


return 0;


}
