67. Add Binary

Given two binary strings a and b, return their sum as a binary string.

Example 1:

Input: a = "11", b = "1"
Output: "100"

Example 2:

Input: a = "1010", b = "1011"
Output: "10101"

Constraints:

• 1 <= a.length, b.length <= 104
• a and b consist only of '0' or '1' characters.
• Each string does not contain leading zeros except for the zero itself.

# @lc code=start
using LeetCode

function add_binary(a::String, b::String)

    num1 = parse(Int64, a; base=2)
    num2 = parse(Int64, b; base=2)

    sum = num1 + num2

    return string(sum, base=2)

end
