Given a non-negative integer num, repeatedly add all its digits until the result has only one digit.


For example:

Given num = 38, the process is like: 3 + 8 = 11, 1 + 1 = 2. Since 2 has only one digit, return it.

class Solution(object):    def addDigits(self, num):        """        :type num: int        :rtype: int        """        result=sum(map(lambda x:int(x),unicode(num)))        if result<10:            return result        return self.addDigits(result)
