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)

m = map(int, raw_input().split())
c = 0

if m[0] < m[1]:
 for i in xrange(m[0],m[1]):
  if i % m[2] == 0:
   c = c + 1
 print c




else:
 for i in xrange(m[0],m[1]):
  if i % m[2] == 0:
   c = c + 1
 print c
