Create a class ShuffleCipher that implements the interface MessageEncoder, as described in Exercise 15. The constructor should have one parameter called n. Define the method encode so that the message is shuffled n times. To perform one shuffle, split the message in half and then take characters from each half alternately. For example, if the message is “abcdefghi”, the halves are “abcde” and “fghi”. The shuffled message is “afbgchdie”. Hint: You may wish to define a private method that performs one shuffle.
What will be an ideal response?
