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)

const input = require('fs').readFileSync('/dev/stdin', 'utf8');

const array = input.split(" ").map(Number);
const a = array[0];
const b = array[1];
const c = array[2];
let count = 0;

for(let i = a;i <= b;i++){
  if(c % i == 0) count++;
}

console.log(count);
