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)


const gInput = require('fs').readFileSync('/dev/stdin', 'utf8')
const [a,b,c] = gInput.split(' ').map( s => parseInt(s))

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