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.

Sample Input

S 12
S 13
H 1
H 2
S 6
S 7
S 8

Solution in JAVA (judge verdict: Wrong Answer)



import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {

	public static void main(String[] args) throws NumberFormatException, IOException {
		// TODO ?????????????????????????????????????????????

		int[] s = new int[13];
		int[] h = new int[13];
		int[] c = new int[13];
		int[] d = new int[13];

		int kazu = Integer.parseInt(br.readLine());
		for (int i = 0; i < kazu; i++) {
			input = br.readLine();
			input2 = input.split(" ");

			if ("S".equals(input2[0])) {// ????????????
				for (int j = 0; j < 13; j++) {
					if (Integer.parseInt(input2[1]) == j - 1) {
						s[j - 1] = Integer.parseInt(input2[1]);
					}
				} // for

			} else if ("H".equals(input2[0])) {// ?????????
