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)

I = input().split()
a = int(I[0])
b = int(I[1])
c = int(I[2])

cnt = 0
while a <= b:
    if c % a == 0:
        cnt += 1
    a += 1

print(str(cnt))
