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

a ≤ b

Sample Input 1

5 14 80

Sample Output 1

3

Solution in JavaScript (judge verdict: Accepted)

let nums = require('fs').readFileSync('/dev/stdin', 'UTF-8').split(' ').map(Number);
const a = nums[0];
const b = nums[1];
const c = nums[2];
let count = 0;
for (let i=a; i<=b; i++) {
  if (c%i===0) count++;
}
console.log(count);
