Why do we use return in c?
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: 1137638147
