java:

简单题重拳出击 芜湖～ 

class Solution {
    public int numberOfSteps(int num) {
        int count = 0;
        while(num != 0){
            if(num % 2 == 0){
                num /= 2;
                count++;
            }else{
                num -= 1;
                count++;
            }
        }
        return count;
    }
}

python3:

class Solution:
    def numberOfSteps(self, num: int) -> int:
        count = 0
        while num != 0:
            if num % 2 == 0:
                num /= 2
                count += 1
            else:
                num -= 1
                count += 1
        return count
