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)

# カードごとの配列の作成
spade, heart, daia, club = Array.new(13, "NG"), Array.new(13, "NG"), Array.new(13, "NG"), Array.new(13, "NG")

# カードの枚数
N = gets.chomp.to_i

# 何が足りないか
def unknown(arr)
	ans_arr = Array.new
	for i in 0..12
		if arr[i] == "NG"
			ans_arr +=  [i]
		end
	end
	return ans_arr
end

# 存在するカード
for i in 1..N
	card = gets.chomp.split("\s")
	number = card[1].to_i - 1

	case card[0]
		when "S"
			spade[number] = "OK"
		when "H"
			heart[number] = "OK"
		when "C"
			club[number] = "OK"
		else
			daia[number] = "OK"
	end
end

# 出力
def output(arr, suit)
	#配列の要素を調べる
	arr_int = arr.length
	
	for k in 0..arr_int - 1
		print(suit, "\s", arr[k] + 1, "\n")
	end
end

s_unknown = unknown(spade)
output(s_unknown, "S")

h_unknown = unknown(heart)
output(h_unknown, "H")

c_unknown = unknown(club)
output(c_unknown, "C")

d_unknown = unknown(daia)
output(d_unknown, "D")
