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())
d =[]
for i in range(c):
    if c%(i+1) == 0:
        d.append(i+1)
cnt = 0
for i in d:
    if a <= i <= b:
        cnt += 1
print(cnt)
