Given a number N, product(N) is the product of the digits of
N. We can then form a sequence N, product(N),
product(product(N))… For example, using 99, we get the
sequence 99, 99 = 81, 81 = 8.

Input Format:
A single integer N

Output Format:

A single integer which is the number of steps after which a
single digit number occurs in the sequence.

Sample Test Cases:

Input #00:
99

Output #00:
2

Explanation:
Step - 1 : 9 * 9 = 81
Step - 2 : 8 * 1 = 8
There are 2 steps to get to this single digit number.

Input #01:
