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;
public class Main{
public static void main(String[]args){
Scanner scan=new Scanner(System.in);
int a=scan.nextInt();
int b[][]=new int[4][13];
int i=0;
int j=0;
String str="";
int num=0;
int mar=0;
do {
	b[i][j]=0;
	j++;
	if(j==13) {
		
		j=0;i++;
	if(i==4) {break;}	
	}
	
}while(true);
i=0;
j=0;
do {
	if(a==i) {break;}
	str=scan.next();
	num=scan.nextInt();
	num-=1;
	if(str.equals("S")) {mar=0;}
	if(str.equals("H")) {mar=1;}
	if(str.equals("C")) {mar=2;}
	if(str.equals("D")) {mar=3;}
	i++;
	b[mar][num]=1;
	}while(true);
i=0;
do {
	if(b[i][j]==0) {
		if(i==0) {
			System.out.println("S "+(j+1));
			
		}	if(i==1) {
			System.out.println("H "+(j+1));
			
		}	if(i==2) {
			System.out.println("C "+(j+1));
			
		}	if(i==3) {

		}
		}
	j++;
