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 JavaScript (judge verdict: WA: Presentation Error)

var input = ""
process.stdin.resume();
process.stdin.setEncoding('utf-8');
process.stdin.on('data', function(chunk) {
  input += chunk;
});
 
process.stdin.on('end', function() {
  arr = [];
  for (i = 0; i < 52; i++) {
    switch (Math.floor(i / 13)) {
      case 0:
        arr.push("S " + (i + 1));
        break;
      case 1:
        arr.push("H " + (i % 13 + 1));
        break;
      case 2:
        arr.push("C " + (i % 13 + 1));
        break;
      case 3:
        arr.push("D " + (i % 13 + 1));
        break;
    }
  }

  
  input = input.split("\n");
  i = 1
  while (input[i] != 0) {
    for (j = 0; j < arr.length; j++) {
      if (arr[j] == input[i]) {
        arr.splice(j, 1);
      }
    }
    i++;
  }
  console.log(arr.join("\n"));
});
