leetcode刷题记录2

介绍

Calculate the sum of two integers a and b, but you are not allowed to use the operator + and -.

Example:
Given a = 1 and b = 2, return 3.

思路

。。。太简单了啊，利用python内置的一些有求和功能的函数来代替+号不就行了，比如列表的sum函数

代码

class Solution(object):
    def getSum(self, a, b):
        """
        :type a: int
        :type b: int
        :rtype: int
        """
        return sum([a,b])
