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
