371. Sum of Two Integers

Given two integers a and b, return the sum of the two integers without using the operators + and -.

Example 1:

Input: a = 1, b = 2
Output: 3

Example 2:

Input: a = 2, b = 3
Output: 5

不用+ 做加法，那用Sum看看，雖然有過，但題目中級，下次做應該要更深入，另外int是不能用sum加，要轉列表。

T:O(n), S:O(1)
class Solution(object):
    def getSum(self, a, b):
        return sum([a,b])
