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.
Example 1:
Input: a = "11", b = "1" Output: "100" Example 2:
Input: a = "1010", b = "1011" Output: "10101"
Constraints:
Each string consists only of '0' or '1' characters. 1 <= a.length, b.length <= 10^4 Each string is either "0" or doesn't contain any leading zero.
