    Enter your code here. Read input from STDIN. Print output to STDOUT

    K = int(input()) rooms = list(map(int, input().split())) unique_rooms = set(rooms)

    captain_room = (sum(unique_rooms) * K - sum(rooms))//(K - 1)

    print(captain_room)

for i in l:
    d[i]=d.get(i,0)+1
for k,v in d.items():
    if v==1:
        print(k)
