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) {
		Scanner sc = new Scanner(System.in);

		String[][] T = new String[14][4];

		T[0][0] = "S";
		T[0][1] = "H";
		T[0][2] = "C";
		T[0][3] = "D";
			

		for(int i = 0; i < 4; i++)
			for (int j = 1; j < 14; j++)
				T[j][i] = "false";

		int n = sc.nextInt();

		String[][] N = new String[n][2];
		for (int i = 0; i < n; i++) {
			N[i][0] = sc.next();
			N[i][1] = sc.next();
			if (N[i][0].equals("S"))
				T[Integer.parseInt(N[i][1])][0] = "true";
			else if (N[i][0].equals("H"))
				T[Integer.parseInt(N[i][1])][1] = "true";
			else if (N[i][0].equals("C"))
				T[Integer.parseInt(N[i][1])][2] = "true";
			else
				T[Integer.parseInt(N[i][1])][3] = "true";
		}

		for(int i = 0; i < 4; i++)
			for (int j = 1; j < 14; j++)
				if(T[j][i].equals("false"))
					System.out.printf("%s %s\n", T[0][i], j);
	}
