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 input = require('fs').readFileSync('/dev/stdin', 'utf8');
var no = input.split(' ').map(Number);
var a = no[0];
var b = no[1];
var c = no[2];
var divisors = [];
for(var i = a; i <= b; i++){
    if(c % i === 0){
        divisors.push(i);
    }
}
console.log(divisors.length);
