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.

Sample Input

47
S 10
S 11
S 12
S 13
H 1
H 2
S 6
S 7
S 8
S 9

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;
class Main {
	int [][] cards = new int [5][15];
	private  static String[] cards2 = {"0","S","H","C","D"};
	int n,j,i,k,cards4,Nu;
	String cards3;
	public void ca() {
		Scanner sc = new Scanner(System.in);
		for(j = 1;j <= 4;j++) {
			for(i = 1 ; i <= 13; i++) {
				k = i;
				cards[j][i] = k;
			}
		}
		n = sc.nextInt();
		for(k = 0 ; k < n - 1; k++) {
			cards3 = sc.next();
			cards4 = sc.nextInt();
			if(cards3.equals( "S" )) {
				Nu = 1;
			} else if(cards3.equals( "H" )) {
				Nu = 2;
			} else if(cards3.equals( "C" )) {
				Nu = 3;
			} else if(cards3.equals( "D" )) {
				Nu = 4;
			}
			switch(Nu) {
				case 1:
					for(j = 1;j <= 13 ; j++) {
						if(cards4 == cards[1][j]) {

						}
					}
					break;
				case 2:

					}
					break;
				default:
					break;
			}
		}
		for(j = 1;j <= 4;j++) {
			for(i = 1;i <= 13;i++) {
				if(cards[j][i] != 0) {
