        int answer = 0;
        for (int num : num_list) {
            while (num != 1) {
                num /= 2;
                answer++;
            }
        }
        return answer;
    }

def solution(num_list):
    answer = 0
    for num in num_list:
        while num != 1:
            num //= 2
            answer += 1
