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())
a = [list(map(str, input().split())) for _ in range(n)]

a.sort()

cS = 0
lc = []
ld = []
lh = []
ls = []

count = 0

#print(len(a))




while True:
    while 'C' == a[cC][0]:
        lc.append(a[cC][1])#no exist
        cC += 1
    cD = cC
    while 'D' == a[cD][0]:
        ld.append(a[cD][1])#no exist
        cD += 1
    cH = cD
    while 'H' == a[cH][0]:
        lh.append(a[cH][1])#no exist
        cH += 1
    cS =cH
    while cS < n:
        ls.append(a[cS][1])#no exist
        cS += 1
    break
