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;

class Main {
	public static void main(String args[]) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		boolean[][] a = new boolean[4][13];
		
		for(int im = 0; im < 4; im++) {
			for(int in = 0; in < 13; in++) {
				a[im][in] = true;
			}
		}
		
		for(int i = 0; i < n; i++){
			String mark = sc.next();
			int num = sc.nextInt() - 1;
			int mar;
			
			if(mark.equals("S")) {
				mar = 0;
			}else if(mark.equals("H")) {
				mar = 1;
			}else if(mark.equals("C")) {
				mar = 2;
			}else {
				mar = 3;
			}
			
			a[mar][num] = false;
		}
		
		for(int im = 0; im < 4; im++) {
			for(int in = 0; in < 13; in++) {
				if(a[im][in]) {
					if(im == 0) {
						System.out.print("S");
					}else if(im == 1) {
						System.out.print("H");
					}else if(im == 2) {
						System.out.print("C");
					}else {
						System.out.print("D");
					}
					
					System.out.println(" " + (in+1));
				}
			}
		}
