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 Python3 (judge verdict: Accepted)

n = int(input())
l_s = []; l_h = []; l_c = []; l_d = []
for i in range(1,n+1):
    l_card = input().split()
    xTyp = l_card[0]
    xNum = int(l_card[1])
    if xTyp == "S": l_s.append(xNum);
    elif xTyp == "H": l_h.append(xNum);   
    elif xTyp == "C": l_c.append(xNum); 
    else: l_d.append(xNum);  

for i in range(1,4+1):
    if i==1: l_lp=l_s;xTyp="S"
    elif i==2: l_lp=l_h;xTyp="H"
    elif i==3: l_lp=l_c;xTyp="C"
    else: l_lp=l_d;xTyp="D"
    if not l_lp == False:
        for k in range(1,13+1):
            if l_lp.count(k)==0:
                print(xTyp,k)
