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 = [int(i) for i in input().split()]

total = 0
for d in range(a, b+1):
      if c % d == 0:
         total += 1
      
print(total)
