Write a method called alternate
that accepts two List
s 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.
