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

S 12
S 13
H 1
H 2
S 6
S 7
S 8

Solution in JAVA (judge verdict: Accepted)

import java.io.*;

class Tranp{
    private int[][] card;
    public Tranp(){
	card=new int[4][];
	for(int i=0;i<4;i++) card[i]=new int[13];
	for(int i=0;i<4;i++){
		for(int j=0;j<13;j++){
		    card[i][j]=0;
		}
	}
    }
    public void markcard(String mark,int num){		   	
	if(mark.equals("S")) card[0][num-1]++;
	else if(mark.equals("H")) card[1][num-1]++;
	else if(mark.equals("C")) card[2][num-1]++;	
	else if(mark.equals("D")) card[3][num-1]++;
    }

    public void printcard(){
	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 if(i==3) System.out.println("D " + (j+1));
		}
	    }
	}
    }
    
}
