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.
attempt: n = int(input())
  cnt = 0
  ml = ["S", "H", "C", "D"]
  s = [[i + 1 for i in range(13)] for i in range(4)]
  while cnt < n:
      M, N = list(input().split())
      N = int(N)
      if M == ml[0]:
          s[0][N - 1] = False
      elif M == ml[1]:
          s[1][N - 1] = False
      elif M == ml[2]:
          s[2][N - 1] = False
      elif M == ml[3]:
          s[3][N - 1] = False
      cnt += 1
  for i in range(len(ml)):
      for j in range(len(s[i])):
          if s[i][j] != False:
              print("{} {}".format(ml[i], s[i][j]))
  
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.
