BJP3 Exercise 11.2: alternate

Language/Type: Java Collections Lists
Author: Aryan Naraghi (on 2013/04/01)

Write a method called alternate that accepts two Lists of integers as its parameters and returns a new List containing alternating elements from the two lists, in the following order:

  • First element from first list
  • First element from second list
  • Second element from first list
  • Second element from second list
  • Third element from first list
  • Third element from second list
  • …

If the lists do not contain the same number of elements, the remaining elements from the longer list should be placed consecutively at the end. For example, for a first list of (1, 2, 3, 4, 5) and a second list of (6, 7, 8, 9, 10, 11, 12), a call of alternate(list1, list2) should return a list containing (1, 6, 2, 7, 3, 8, 4, 9, 5, 10, 11, 12). Do not modify the parameter lists passed in.
