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.

Constraints

* 1 ≤ a, b, c ≤ 10000
* a ≤ 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.

Example

Input

5 14 80


Output

3
```python
a, b, c = map(int, input().split())
ans = 0
for i in range(a, b + 1):
	if c % i == 0:
		ans += 1
print(ans)
