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: Wrong Answer)

        'use strict';
(function(stdin) {
  var inputs  = stdin.toString();
  var a = inputs[0];
  var b = inputs[1];
  var c = inputs[2];
  var zero = 0;
for (var a = a; c <= b; c++);{
    if(c % a === 0)zero++;
}

}(require('fs').readFileSync('/dev/stdin', 'utf8')));
