output_description: Print the missing cards. The same as the input format, each card should be
  printed with a character and an integer separated by a space character in a
  line. Arrange the missing cards in the following priorities:
  
    * Print cards of spades, hearts, clubs and diamonds in this order.
    * If the suits are equal, print cards with lower ranks first.
input_description: In the first line, the number of cards n (n ≤ 52) is given.
  
  In the following n lines, data of the n cards are given. Each card is given by
  a pair of a character and an integer which represent its suit and rank
  respectively. A suit is represented by 'S', 'H', 'C' and 'D' for spades,
  hearts, clubs and diamonds respectively. A rank is represented by an integer
  from 1 to 13.

problem_description: Finding Missing Cards
  
  Taro is going to play a card game. However, now he has only n cards, even
  though there should be 52 cards (he has no Jokers).
  
  The 52 cards include 13 ranks of each of the four suits: spade, heart, club
  and diamond.
