1. Write a function that takes a string representing 5 playing cards and returns the highest scoring card.
   • Input 5 space delimited strings
   • Each string is comprised of two parameters:
     • value 2,3,4,5,6,7,8,9,10,J,Q,K,A
     • suit C,D,H,S
   • e.g.
     2C = Two of clubs
     QS = Queen of spades
     
   • "2H 3D 5S 9C KD" should result in the KD card

2. Create a function that takes two players and reports the winner and their winning card. The winner is the player with highest card.
   
   • e.g. "2H 3D 5S 9C QD", "2C 3H 4S 8C KH" -> "2C 3H 4S 8C KH", "KH"

2H 4S 4C 2D 4H	2S 8S AS QS 3S	Player 1 wins - with full house: 4 over 2
