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)

##S->H->C->D
$array=Array.new(4).map{Array.new(14, 0)}
$suits=["S","H","C","D"]
N=gets.to_i
i=0
def suit(str)
 if(str=="S")
  return 0
 elsif(str=="H")
  return 1
 elsif(str=="C")
  return 2
 else
  return 3
end
end
while(i<N)
s,a=gets.chomp.split(" ").map(&:to_s);
 $array[suit(s)][a.to_i]=1
i=i+1
end
for m in 0..3 do
 for n in 1..13 do
  if$array[m][n]==0
   print("#{$suits[m]} #{n}\n")
  end
 end
end
