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)

function Main(input) {
  let args = input
    .trim()
    .split(" ")
    .map((x) => parseInt(x, 10));
  let a = args[0];
  let b = args[1];
  let c = args[2];

  let ans = 0;
  for (let x = a; x <= b; x++) {
    if (c % x === 0) {
      ans++;
    }
  }
  console.log(ans);
}

Main(require("fs").readFileSync("/dev/stdin", "utf8"));
