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 kb = new Scanner( System.in );

		String str = kb.nextLine();
		int n = Integer.parseInt( str );
		
		boolean[] cards= new boolean[53]; 
		for( int i=0; i<n; i++ ) {
			String pattern = kb.next();
			int num = kb.nextInt();
			if( "S".equals(  pattern ) ) {
				cards[ num-1 ]=true;
			} else if( "H".equals(  pattern ) ) {
				cards[ 12+num ]=true;
			} else if( "C".equals(  pattern ) ) {
				cards[ 25+num ]=true;
			} else if( "D".equals(  pattern ) ) {
				cards[ 38+num ]=true;			
			}
		}

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