countDigits


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


countDigits(126) → 3
countDigits(49) → 2
countDigits(12) → 2

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

public int countDigits(int n) { }
