Problem:
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.

Input

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.

Output

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.

Solution in Ruby (judge verdict: WA: Presentation Error)

cards = ['S 1', 'S 2', 'S 3', 'S 4', 'S 5', 'S 6', 'S 7', 'S 8', 'S 9', 'S 10', 'S 11', 'S 12', 'S 13', 'H 1', 'H 2', 'H 3', 'H 4', 'H 5', 'H 6', 'H 7', 'H 8', 'H 9', 'H 10', 'H 11', 'H 12', 'H 13', 'C 1', 'C 2', 'C 3', 'C 4', 'C 5', 'C 6', 'C 7', 'C 8', 'C 9', 'C 10', 'C 11', 'C 12', 'C 13', 'D 1', 'D 2', 'D 3', 'D 4', 'D 5', 'D 6', 'D 7', 'D 8', 'D 9', 'D 10', 'D 11', 'D 12', 'D 13']
gets.to_i.times do
  cards.delete(gets.chomp)
end
puts cards.join("\n") if cards.size
