Given an ArrayList of Integers called lst, add a new element at position pos, with the same value as the old element at pos. Thus, if pos is 0 and the element at index 0 has the value 3, your code would insert an additional Integer element with the value 3 such that the first two elements both now have the value 3. Return the ArrayList as output.

ArrayList<Integer> myList = new ArrayList<Integer>();
myList.add(5); // myList contents: [5]
myList.add(2); // myList contents: [5, 2]
myList.add(1, 3); // myList contents: [5, 3, 2]
System.out.println(myList.get(1)); // prints 3 (element at index 1)
myList.add(myList.get(0)); // myList contents: [5, 3, 2, 5]
