LeetCode 1980 | Find Unique Binary String | Python

In this video we break down LeetCode 1980 – Find Unique Binary String using a powerful mathematical idea called Cantor’s Diagonalization. Instead of brute forcing all possible binary strings, we construct a guaranteed unique string by flipping the diagonal bits of the input list. This elegant trick allows us to solve the problem in O(n) time. You’ll learn: • The intuition behind the diagonal trick • Why the constructed string is guaranteed to be unique • Step-by-step algorithm explanation • Clean Python implementation • Interview insights and common mistakes Problem Details Problem: 1980. Find Unique Binary String Difficulty: Medium Category: Greedy / Bit Manipulation / Construction Language: Python This concept also appears in advanced algorithm interviews and theoretical computer science through Cantor’s diagonal argument. If you're preparing for coding interviews or improving your DSA problem-solving skills, this is a must-know trick. Subscribe for more clear LeetCode explanations and algorithm breakdowns.
