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 = map(int,input().split()) ;
count = 0 ;
for i in range(a,b+1) :
  d = c % i ;
  if d == 0 :
     count = count +1  
print("%d" % count)
