Given an ArrayList of Integers, replace the third element with the val parameter. Return the modified ArrayList. 


Precondition: lst will have at least 3 elements.


HINT:  Remember that indexes start at 0...

apcsaListReplaceThird([5, 1, 2], 5) → [5, 1, 5]
apcsaListReplaceThird([5, 1, 5], 5) → [5, 1, 5]
apcsaListReplaceThird([0, 1, 2, 3], -1) → [0, 1, -1, 3]
...Save, Compile, Run (ctrl-enter)
public ArrayList<Integer> apcsaListReplaceThird(ArrayList<Integer> lst, int val) {
  
}
