Given a positive integer, recursively apply a step of the Collatz sequence. Each step obeys the following rules: 


-If the number is even, divide it by 2.


-If the number is odd, multiply it by 3 and add 1.


Return how many steps it takes to reach the number 1.

apcsaRecurCollatz(1) → 0
apcsaRecurCollatz(2) → 1
apcsaRecurCollatz(3) → 7
...Save, Compile, Run (ctrl-enter)
public int apcsaRecurCollatz(int n) {
  
}
