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 Scala (judge verdict: Accepted)

object Main {
  val Suits = Array('S', 'H', 'C', 'D')

  def main(args: Array[String]): Unit = {
    val scanner = new java.util.Scanner(System.in)
    val n = scanner.nextInt()

    val deck = Array.ofDim[Boolean](Suits.length, 13)

    Iterator.from(0, 1)
      .takeWhile(_ < n)
      .map(_ => (scanner.next(), scanner.nextInt() - 1))
      .foreach {
        case ("S", rank) => deck(0)(rank) = true
        case ("H", rank) => deck(1)(rank) = true
        case ("C", rank) => deck(2)(rank) = true
        case ("D", rank) => deck(3)(rank) = true
        case _ =>
      }

    deck
      .zipWithIndex
      .flatMap { case (cards, s) =>
        cards
          .zipWithIndex
          .collect { case (false, i) => i }
          .map(i => s"${Suits(s)} ${i + 1}")(collection.breakOut)
      }
      .foreach(println)
  }
