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 C (judge verdict: Time Limit Exceeded)

#include<stdio.h>
int main()
{
	int a=3, b=13, c, d, e, f, g, kado[4][14];
	char A, B, C;
	for (b = 0; b < 4; b++){
		for (a = 1; a < 14; a++){
			kado[b][a] = 1;
		}
	}
	scanf("%d", &a);
	for (b = 1; b <= a; b++){
		scanf("%c %d", &A, &c);
		switch (A){
		case 'S':kado[0][c] = 0; break;
		case 'H':kado[1][c] = 0; break;
		case 'C':kado[2][c] = 0; break;
		case 'D':kado[3][c] = 0; break;

		}


		for (b = 0; b < 4; b++){
			for (a = 1; a < 14; a++){
				if (kado[b][a]){
					switch (b){
					case 0:printf("S %d\n", a);
						break;
