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)

def main():
    inp = input()
    x, y, z = tuple(map(int, inp.split()))
    count = 0
    for i in range(x, y + 1):
        count += 1 if z % i == 0 else 0
    print(count)

if __name__ == '__main__':
    main()
