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

Sample Output 1

3

Solution in Kotlin (judge verdict: Accepted)

fun main(args: Array<String>) {
    val (a, b, c) = readLine()!!.split(" ").map { it.toInt() }
    var x = 0
    for (n in a..b) {
        if (c % n == 0) {
            x ++
        }
    }
    println(x)
}
