    I couldn't help myself. 

    from collections import Counter

input()

print(Counter(list(map(int,input().split()))).most_common()[:-2:-1][0][0])

    size=int(input()) Room_Number=list(map(int,input().split()))

    captain = (sum(set(Room_Number)) * size - sum(Room_Number)) // (size - 1) print(captain)

    if __name__ == '__main__':
    size =int(input())
    room_num = list(map(int,input().split()))
    
    set_rn = set(room_num)
    
    for i in set_rn:
        room_num.remove(i)
    
    set_rn.symmetric_difference_update(room_num)
    
    print(int("".join(str(i) for i in set_rn)))

    K = int(input())
arr= list(input().split())
s =set(arr)

for ch in s:
    arr.remove(ch)
temp = s.difference(set(arr))
print("".join(temp))

    solve it by using dict add the values and just call the value whose count is one thats the captain room

    k = int(input()) rooms = list(map(int,input().split()))

    dict1 = {}

    for i in rooms: dict1[i]= dict1.get(i,0)+ 1

    for keys,values in dict1.items(): if values == 1: print(keys)
