Write a method called alternate that accepts two Lists 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].
