Fred has a deck of 52 playing cards that have been thoroughly shuffled. He has asked you to determine several things related to reordering them: 1. What modification to bitonic mergesort will be needed to sort the cards, given that there are four suits (spades, hearts, clubs, and hearts)? 2. How many friends will Fred have to invite over (and feed) to carry out a modified bitonic mergesort in parallel, and how many steps will each friend have to carry out?
