productDigits


Given a non-negative int n, return the product of its digits recursively (no loops). Note that mod (%) by 10 yields the rightmost digit (126 % 10 is 6), while divide (/) by 10 removes the rightmost digit (126 / 10 is 12).


productDigits(126) → 12
productDigits(49) → 36
productDigits(12) → 2

...Save, Compile, Run (ctrl-enter)

public int productDigits(int n) { }
