Contest 2: Find all factors

Description

Output the number of total factors of an integer.

Input

There are several lines. And each line contains a positive number N (1<=N<=9999999999999999).

Output

Output the number of total factors for each N.

For example,

Input

12

20

Output

6

6

Because 1, 2, 3, 4, 6, 12 are factors of 12.

1,2,4,5,10,20 are are factors of 20.

Sample Input

1220

Sample Output

66
