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)

start, fin, target = [int(x) for x in input().split()]
c = 0
for x in range(start, fin+1):
  if target % x == 0 and x >= start and x <= fin:
    c += 1
print(c)
