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: Accepted)

import java.util.Scanner;

public class Main{
	public static void main(String args[]){

		//???????????£?¨??????????
		int Card [][];
		Card = new int[4][13];

		//????????°????????????????????????????????????
		Scanner sc = new Scanner(System.in);
		int N = sc.nextInt();


		//N?????°?????????
		for(int i = 0; i < N ; i++){

			//????????¨??°???????????£?????????
			String Mark = sc.next();
			int Suji = sc.nextInt();

			//?????????S?????£??????1
			if(Mark.equals ("S")){
				//??£??\??????
				Card[0][Suji-1] = 1;
			}
			//?????????H?????£??????1
			if(Mark.equals ("H")){
				//??£??\??????
				Card[1][Suji-1] = 1;
			}
			//?????????C?????£??????1
			if(Mark.equals ("C")){
				//??£??\??????
				Card[2][Suji-1] = 1;
			}
			//?????????D?????£??????1
			if(Mark.equals ("D")){
				//??£??\??????
				Card[3][Suji-1] = 1;
			}
		}

		//?????£??????????????¨
		for (int i = 0; i < 4; i++){
			for (int j = 0; j < 13; j++){
				//1??????????????£????????????
				if(Card[i][j] == 0){

					//0?????£??????S
					if(Card[i] == Card[0]){
						System.out.println("S " + (j + 1));
					//1?????£??????H
					}else if(Card[i] == Card[1]){
						System.out.println("H " + (j + 1));
					//2?????£??????C
					}else if(Card[i] == Card[2]){

					//3?????£??????D
					}else if(Card[i] == Card[3]){
						System.out.println("D " + (j + 1));
