    1980 - Find Unique Binary String.

    Medium

    Given an array of strings nums containing n unique binary strings each of length n, return a binary string of length n that does not appear in nums. If there are multiple answers, you may return any of them.

    Example 1:

    Input: nums = [“01”,“10”]

    Output: “11”

    Explanation: “11” does not appear in nums. “00” would also be correct.

    Example 2:

    Input: nums = [“00”,“01”]

    Output: “11”

    Explanation: “11” does not appear in nums. “10” would also be correct.

    Example 3:

    Input: nums = [“111”,“011”,“001”]

    Output: “101”

    Explanation: “101” does not appear in nums. “000”, “010”, “100”, and “110” would also be correct.

    Constraints:

    • n == nums.length
    • 1 <= n <= 16
    • nums[i].length == n
    • nums[i] is either '0' or '1'.
    • All the strings of nums are unique.
