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 Ruby (judge verdict: Wrong Answer)

aryQuestion = gets.split.map(&:to_i);
 
a = aryQuestion[0];
b = aryQuestion[1];
c = aryQuestion[2];
 
count = 0;
 
for num in a..b do
	puts (c % num).to_s;
	if (c % num) == 0 then
		count.next;
	end
 
end
 
puts count.to_s;
