Longest_suit: Application Concept: Identify the suit with the most cards, and return the cards in that suit. Given a list of tuples, identify the longest subset that can be found with the same encoded suit (the second value in each tuple). For example, longest_suit([(1,3),(2.1),(3,2),(3, 3)]) returns [(1,3),(3,3)]Hint: first divide all the cards into the four separate lists, and then decide which list is longest. If two suits happen to have the same number of cards, it does not matter which is returned. This function is only of interest for identifying flushes and straight flushes, where five are of the same suit.
