Given an ArrayList of Integers, the value of the first element is the index to replace, and the value of the second element is the new value for the replaced element. Return the modified ArrayList. 


Precondition: lst will have enough elements.  The first element will have a value greater than or equal to 0.

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