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.util.Scanner;

public class Main {
	public static void main(String[] args){
		Scanner std = new Scanner(System.in);
		int n = Integer.parseInt(std.next());

		int array[];
		array = new int[53];
		for(int i=1; i<=52; i++){
			array[i] = i;
		}

		for(int j=1; j<=n; j++){
			String suit = std.next();
			int rank = Integer.parseInt(std.next());
			if(suit.equals("S")) {rank+=0;}
			else if(suit.equals("H")) {rank+=13;}
			else if(suit.equals("C")) {rank+=26;}
			else if(suit.equals("D")) {rank+=39;}

			array[rank] = 0;
		}

		for(int i=1; i<=52; i++){
			if(array[i]!=0){
				String ret = "";
				if((i-1)/13==0){ret+="S ";}
				else if((i-1)/13==1){ret+="H ";}
				else if((i-1)/13==2){ret+="C ";}
				else if((i-1)/13==3){ret+="D ";}
				ret += i%13;
				System.out.println(ret);
			}
		}
	}
