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.io.*;
 
class Main{
 public static void main(String[] args)throws IOException{
  BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
  int num,i,j;
  num = Integer.parseInt(br.readLine());
  int[][] cards = new int[4][13];   
   for(i=0;i<4;i++){
    for(j=0;j<13;j++){
     cards[i][j]=0;
    }
   }
 
   for(i=0;i<num;i++){ 
    String str = br.readLine(); 
    String[] strAry = str.split(" ");
    String op = strAry[0];
    int number = Integer.parseInt(strAry[1]);
    number--;   
 
    if(op.equals("S")){            
      cards[0][number]=1; 
    }else if(op.equals("H")){
      cards[1][number]=1;
    }else if(op.equals("C")){
      cards[2][number]=1;

   }
     
   for( i=0;i<4;i++){
    for(j=0;j<13;j++){
     if(cards[i][j]==0){
       if(i==0){   
         System.out.println("S "+ (j+1));     
       }else if(i==1){
