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)

ABC = input().split()
a = int(ABC[0])
b = int(ABC[1])
c = int(ABC[2])
i = 0
while a<=b:
    if c%a==0:
        i = i+1
    a = a+1
print(i)
