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)

num = int(input())

S = [x for x in range(1,14)]
H = [x for x in range(1,14)]
C = [x for x in range(1,14)]
D = [x for x in range(1,14)]

for i in range(num):
    s = input().split()
    
    if s[0]=="S":        
        S.remove(int(s[1]))
    elif s[0]=="H":        
        H.remove(int(s[1]))
    elif s[0]=="C":        
        C.remove(int(s[1]))
    elif s[0]=="D":        
        D.remove(int(s[1]))
    
for i in range(len(S)):
    print("S",S[i])
for i in range(len(H)):
    print("H",H[i])
for i in range(len(C)):
    print("C",C[i])
for i in range(len(D)):
    print("D",D[i])
