1665. 计算数字

class Solution:
    """
    @param num: the num
    @return: the array subject to the description
    """
    ‘‘‘
    大致思路:
    1.转二进制[2:],取出1个个数，写入res里面，循环，依次将1的位置append到res里面，返回
    ‘‘‘
    def calculateNumber(self, num):
        bin_num = bin(num)[2:]
        res = [bin_num.count(‘1‘)]
        for i in range(len(bin_num)):
            if bin_num[i] == ‘1‘:
                res.append(i+1)
        return  res
