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[] arg){
    int n;
    int [][] card = new int[4][13];

    for(int i=0; i<4; i++)
        for(int j=0; j<13; j++)
            card[i][j] = 0;

    Scanner in = new Scanner(System.in);

    n = in.nextInt();

    String mark;
    int su;

    for(int i=0; i<n; i++){
        in.nextLine();
        mark = in.next();
        su = in.nextInt();

        if(mark.equals("S"))
            card[0][su-1] = 1;
        else if(mark.equals("H"))
            card[1][su-1] = 1;
        else if(mark.equals("C"))
            card[2][su-1] = 1;
        else
            card[3][su-1] = 1;
    }

    for(int i=0; i<4; i++)
        for(int j=0; j<13; j++)
            if(card[i][j] == 0){
                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));
            }
  }
