Solution: Single Element in a Sorted Array

Explore how to apply a modified binary search to locate the unique element in a sorted array where every other element appears twice. Understand the use of even and odd indices, pointer movement strategies, and achieve an efficient O(log n) time and O(1) space solution.

Statement

You are given a sorted array of integers, nums, where all integers appear twice except for one. Your task is to find and return the single integer that appears only once.

The solution should have a time complexity of O(logn)O(\log n) or better and a space complexity of O(1)O(1).

Constraints:

  • 11 \leq ...
