You're working with two lists: LinkedList and ArrayList that contain String elements.
You need to implement the removeTheSame method. It should remove equal elements at equal indexes.
Note that both lists always have the same size.
Example:
// original lists
LinkedList [a, b, c, d, e, f]
ArrayList [a, 1, 2, 3, 4, f]
// after removeTheSame method invocation
LinkedList [b, c, d, e]
ArrayList [1, 2, 3, 4]
