Given an ArrayList of Integers called lst, add a new element num at the end of the ArrayList. Return the ArrayList as output. 

HINT
The add method with one parameter will add to the end of the ArrayList. Easy-peasy!

apcsaListAddEnd([3, 4, 5], 2) → [3, 4, 5, 2]
apcsaListAddEnd([5, 0, 3], 0) → [5, 0, 3, 0]
apcsaListAddEnd([3, 5, 6], 1) → [3, 5, 6, 1]

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

public ArrayList<Integer> apcsaListAddEnd(ArrayList<Integer> lst, int num) { }
