Single Element in a Sorted Array | Leetcode 540 | Binary Search DSA Series Day #12
📌 Welcome to Day 12 of our Binary Search DSA Playlist!
In this video, we’re solving a classic Leetcode problem — Find the single element in a sorted array where every other element appears twice using an efficient binary search approach.
🧠 Problem Summary:
You're given a sorted array where every element appears exactly twice, except for one element that appears only once.
Your task is to find that unique element in O(log n) time complexity using binary search — without using extra space.
👨💻 What You'll Learn:
✅ How to use index parity (even/odd) to guide binary search
✅ Pattern recognition in paired elements
✅ Dry run + step-by-step binary search breakdown
✅ Full C++ solution with explanation
✅ Interview tricks and edge case handling
✅ Time Complexity: O(log n)
✅ Brute Force (for comparison): O(n)
