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: Wrong Answer)

(function(input) {
    var a = parse(input, ',');
    var cards = makeCards();
    for (var i = 1; i < a.length; i++) {
        var c = a[i][0];
        delete cards[c];
    }
    console.log(Object.keys(cards).join('\n'));
})(require('fs').readFileSync('/dev/stdin', 'utf8'));

function parse(str, sep, ter) {
    sep = sep || ' ';
    ter = ter || '\n';
    str = str.replace(/\n$/, '');
    var a = str.split(ter);
    for (var i = 0; i < a.length; i++) {
        a[i] = a[i].split(sep);
    }
    return a;
}

function makeCards() {
    var ts = ['S', 'H', 'C', 'D'];
    var a = [];
    for (var i = 0; i < ts.length; i++) {
        var t = ts[i];
        for (var j = 1; j <= 12; j++) {
            a[t + ' ' + j] = 1;
        }
    }
    return a;
}
