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 JavaScript (judge verdict: Accepted)

var x = require('fs').readFileSync('/dev/stdin', 'utf8');
var arr = x.split(/\s/);
a = arr[0];
b = arr[1];
c = arr[2];
var count = 0;
for (i = 1 ; i <= c; i++) {
  if ((c%i == 0) && (a <= i) && (i <= b))
    count++;
}
console.log(count);
