두 수의 연산값 비교하기

def solution(a, b):
    cond1 = str(a) + str(b)
    cond2 = 2 * a * b
    return max(int(cond1), cond2)

 

배열 비교하기

def solution(arr1, arr2):
    sum_arr1 = sum(arr1)
    sum_arr2 = sum(arr2)

    if len(arr1) < len(arr2):
        return -1
    
    if len(arr1) > len(arr2):
        return 1

    if len(arr1) == len(arr2):
        if sum_arr1 < sum_arr2:
            return -1
        elif sum_arr1 == sum_arr2:
            return 0
        elif sum_arr1 > sum_arr2:
            return 1
