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 Python3 (judge verdict: Accepted)

# coding: utf-8

a, b, c = map(int, input().split())

i = a
j = 0
while i <= b:
    if c % i == 0:
        j += 1
    i += 1
print(j)
