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: Wrong Answer)

sCard = [0] * 13
hCard = [0] * 13 
cCard = [0] * 13
dCard = [0] * 13

callNum = int(input())

for cardLoop in range(callNum):
    symbol, cardNum = input().split()
    cardNum = int(cardNum)
    if symbol == "S":
        sCard[cardNum-1] = cardNum
    elif symbol == "H":
        hCard[cardNum-1] = cardNum
    elif symbol == "C":
        cCard[cardNum-1] = cardNum
    elif symbol == "D":
        dCard[cardNum-1] = cardNum

sLack = 0
hLack = 0
cLack = 0
dLack = 0

for cardLoop in range(13):
    if sCard[cardLoop] == 0:
        sLack = sLack + 1
    if hCard[cardLoop] == 0:
        hLack = hLack +1
    if cCard[cardLoop] == 0:
        cLack = cLack +1    
    if dCard[cardLoop] == 0:
        dLack = dLack +1

print("S " + str(sLack))
print("H " + str(hLack))
print("C " + str(cLack))
print("D " + str(dLack))
