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

Solution in Kotlin (judge verdict: Accepted)

fun main(args: Array<String>) {
    val input = readLine()?.split(' ')?.map{Integer.parseInt(it)} ?: listOf(0,0,0)
    println((input[0]..input[1]).toList().count {input[2] % it == 0 })
}
