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;

class Main
{
	public static void main ( String[] args ) {
		
		Scanner  sc = new Scanner ( System.in );
		StringBuilder str = new StringBuilder ();
		
		boolean [][] cards = new boolean[ 4 ][ 13 ];
		
		int n = sc.nextInt ();
		
		for ( int i = 0; i < n; i++ ) {
			String art = sc.next ();
			int rank = sc.nextInt ();
			
			if ( art.equals ( "S" ) ) {
				cards[ 0 ][ rank - 1 ] = true;
			} else if ( art.equals ( "H" ) ) {
				cards[ 1 ][ rank - 1 ] = true;
			} else if ( art.equals ( "C" ) ) {
				cards[ 2 ][ rank - 1 ] = true;
			} else {
				cards[ 3 ][ rank - 1 ] = true;
			}
		}
		for ( int i = 0; i < 4; i++ ) {
			for ( int j = 0; j < 13; j++ ) {
				if ( !cards[ i ][ j ] ) {
					if ( i == 0 ) {
						System.out.println ( "S" + ( j + 1 ) );
					} else if ( i == 1 ) {
						System.out.println ( "H" + ( j + 1 ) );
					} else if ( i == 2 ) {
						System.out.println ( "C" + ( j + 1 ) );
					} else {
						System.out.println ( "D" + ( j + 1 ) );
