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)

def solve(line):
    a = line[0]
    b = line[1]
    c = line[2]
    c_divisors=[]
    count=0
    for i in range(1,c+1):
        if c%i==0:
            c_divisors.append(i)
    
    for x in range(a,b+1):
        if x in c_divisors:
            count+=1
    print(count)



    
def answer():
    line = list(map(int,input().split()))
    solve(line)
