Write a method that takes an ArrayList of Strings, and an int numRepeats and returns a new ArrayList with the original ArrayList repeated numRepeats times.

For example if we had an ArrayList<String> list with the values [“a”, “b”, “c”]:

repeatArrayList(list, 3)

Should return a new ArrayList with the elements:

["a", "b", "c", "a", "b", "c", "a", "b", "c"]
