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)

process.stdin.setEncoding('utf-8');
process.stdin.on('data', input => {
  var arry = input.split(' ').map(Number);
  var a = arry[0]
  var b = arry[1]
  var c = arry[2]

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

  console.log(result);
})
