One line python without bin()


  • 0

    I don't think the interviewer will allow bin() function for this problem...

    class Solution(object):
        def hammingWeight(self, n):
            """
            :type n: int
            :rtype: int
            """
            return (n & 1) + self.hammingWeight(n >> 1) if n != 0 else 0
