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: Wrong Answer)

using System;

class Program
{
    static void Main()
    {
        int c = int.Parse(Console.ReadLine());
        string[] inStr;
        
        string wk = "";
        for (int i = 1; i <= 13; i++) { wk = wk + i.ToString() + " "; }
        
        string[] t = new String[4];
        t[0] = wk;
        t[1] = wk;
        t[2] = wk;
        t[3] = wk;
        
        for (int i = 0; i < c; i++)
        {
            inStr = Console.ReadLine().Split(' ');
            
                 if (inStr[0] == "S") { t[0].Replace(inStr[1] + " ", ""); }
            else if (inStr[0] == "H") { t[1].Replace(inStr[1] + " ", ""); }

            else if (inStr[0] == "D") { t[3].Replace(inStr[1] + " ", ""); }
        }
        
        string result = "";
        string[] a;
        
        //結果を表示
        for (int i = 0; i < 4; i++)
        {
            if (!t[i].TrimEnd().Equals(""))
            {
                a = t[i].TrimEnd().Split(' ');
                
                for (int j = 0; j < a.Length - 1; j++)
                {
                    if (!a[j].TrimEnd().Equals(""))

                             if (i == 0) { result = "S "; }
                        else if (i == 1) { result = "H "; }
                        else if (i == 2) { result = "C "; }
                        else if (i == 3) { result = "D "; }
                        
                        result = result + a[j].TrimEnd();
                        Console.WriteLine(result);
                    }
