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)

var lines = [];
var reader = require('readline').createInterface({
  input: process.stdin,
  output: process.stdout
});
reader.on('line', function (line) {
  var i,cnt=0;
  var a = line.split(' ');
  var c = parseInt(a[0],10);
  var d = parseInt(a[1],10);
  var e = parseInt(a[2],10);
  for(i=c;i<=d;i++){
    if(e%i==0)
      cnt = cnt + 1;
  }
  console.log(cnt);
  process.exit();
});
process.stdin.on('end', function () {
});
