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: Accepted)

num = gets.to_i
s = []
h = []
c = []
d = []

def look_for_lost(kind, a)
  a = a.sort
  for i in 1..13 do
    flag = false
    a.each do |x|
      if x == i then flag = true end
    end
    if flag == false then puts "#{kind} #{i}" end
  end
end

for i in 1..num do
  card = gets.chomp
  case card.split(" ")[0]
  when "S" then
    s << card.split(" ")[1].to_i
  when "H" then
    h << card.split(" ")[1].to_i
  when "C" then
    c << card.split(" ")[1].to_i
  when "D" then
    d << card.split(" ")[1].to_i
  end
end

look_for_lost("S", s)
look_for_lost("H", h)
look_for_lost("C", c)
look_for_lost("D", d)
