Symmetric Difference

problem link : https://www.hackerrank.com/challenges/symmetric-difference/problem?h_r=next-challenge&h_v=zen

difficulty : easy

Tip

• sorted() not sort() :-) is to sort items in a list
• one set = M - N
• other set = N - M
• one set.update(other set)
• covert set to list
• sort list
• it's not a tip, it is almost solution :)

Solution

m = int(input()) Ms = set(map(int, input().split())) n = int(input()) Ns = set(map(int, input().split())) Us = Ms.difference(Ns) Us.update(Ns.difference(Ms)) print(*sorted(list(Us)), sep='\n')
