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: Wrong Answer)

import java.io.*;
public class Main {
	public static void main(String[] args)throws IOException  {
		BufferedReader a=new BufferedReader(new InputStreamReader(System.in));
		String n=a.readLine();
		int s=Integer.parseInt(n);
		int[] k;k=new int[53];int e=0;
		for(int z=1;z<=s;z++){
			String x=a.readLine();
			String[] i=x.split(" ");
			e=Integer.parseInt(i[1]);
			if (i[0].equals("S"))k[e]=1;
			else if(i[0].equals("H"))k[e+13]=1;
			else if(i[0].equals("C"))k[e+26]=1;
			else if(i[0].equals("D"))k[e+39]=1;
		}
		int m=52-s;int c=0;int f=0;
		for(int z=1;z<=52;z++){
			if(k[z]==1)continue;
			e=z/13;f=z-e*13;
			if(e==0)
				System.out.println("S "+f);
			else if(e==1)
				System.out.println("H "+f);
			else if(e==2)
				System.out.println("C "+f);
			else if(e==3)
				System.out.println("D "+f);
			c++;
			if(m==c)break;
		}
	}
