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: WA: Presentation Error)

import java.util.Scanner;

public class Main {
	public static void main(String [] args) {
		Scanner stdIn = new Scanner(System.in);
		int n, x;
		String c;
		boolean dataS[] = new boolean[13];
		boolean dataH[] = new boolean[13];
		boolean dataC[] = new boolean[13];
		boolean dataD[] = new boolean[13];
		
		for(int i = 0; i < 13; i++) {
			dataS[i] = false;
			dataH[i] = false;
			dataC[i] = false;
			dataD[i] = false;
		}
		
		n = stdIn.nextInt();
		
		for( int i = 1; i <= n; i++) {
			c = stdIn.next();
			x = stdIn.nextInt();
			
			switch(c) {
			case "S":
				dataS[x - 1] = true;
				break;
			case "H":
				dataH[x - 1] = true;
				break;
			case "C":
				dataC[x - 1] = true;
				break;
			case "D":
				dataD[x - 1] = true;
				break;
			default:
				break;
			}
		}
		
		for(int i = 0; i < 4; i++) {
			for(int j = 1; j <= 13; j ++) {
				switch(i) {
				case 0:
					if(dataS[j - 1] == false) {
						System.out.println("S　" + j);
					}
					break;
				case 1:
					if(dataH[j - 1] == false) {
						System.out.println("H　" + j);
					}
					break;
				case 2:
