Add Binary

Given two binary strings, return their sum (also a binary string). The input strings are both non-empty and contains only characters 1 or 0.
（二进制字符串加法）

Example:

1. 十进制 & 二进制转换

class :
    def addBinary(self, a, b):
        """
        :type a: str
        :type b: str
        :rtype: str
        """
        a = int(a, 2)
        b = int(b, 2)
        return "{:b}".format(a + b)
