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 Python (judge verdict: Wrong Answer)

import math

inp = raw_input().strip().split()

a = int(inp[0])
b = int(inp[1])
c = int(inp[2])
n = 0
for i in range(a,b):
    if c%i == 0:
        n += 1

print n
