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 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 IOException {
		BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
		// ????????????????????°????????????????????????
		int Mark = 4;
		int Num = 13;
		// ????????????????????°????????????????????????
		int cards_Array[][] = new int[Mark][Num];
		String cards = input.readLine();
		// ?????£??????????????????????????°?????????
		int num_of_T = Integer.parseInt(cards);
		int mark_num = 0;
		int card_num = 0;

		for (int i = 0; i < num_of_T; i++) {
			String input_b = input.readLine();
			String[] strAry = input_b.split(" ");
			// ??????????????????
			String T_Mark = strAry[0];
			// ?????????????????????????????\??????????????¨??????????????????
			if (T_Mark.equals("S")) {
				mark_num = 0;
			} else if (T_Mark.equals("H")) {
				mark_num = 1;
			} else if (T_Mark.equals("C")) {
				mark_num = 2;
			} else if (T_Mark.equals("D")) {
				mark_num = 3;
			}
			// ?????????????????°
			card_num = Integer.parseInt(strAry[1]);
			cards_Array[mark_num][card_num - 1] = 1;
		}
              //??????????????°
		for (int design_gr = 0; design_gr < Mark; design_gr++) {
			//??°???
			for (int number_gr = 0; number_gr < Num; number_gr++) {
				// ??????Array???????´??????????Array_input???????´?????????????
				if (cards_Array[design_gr][number_gr] != 1) {
					int cards_of_re = number_gr + 1;
					if (number_gr == 0) {
						System.out.println("S" + " " + cards_of_re);
					} else if (number_gr == 1) {
						System.out.println("H" + " " + cards_of_re);
					} else if (number_gr == 2) {
						System.out.println("C" + " " + cards_of_re);
					} else {
