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)

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

ans = 0
num = a

while True:
    if c%num == 0:
        ans += 1
    num += 1
    if num > b:
        break

print(ans)
