Solution: Single Element in a Sorted Array

Explore how to apply a modified binary search to find the single non-duplicate integer in a sorted array where every other element appears twice. Understand pointer manipulation and indexing strategies that result in an optimal O(log n) time and O(1) space complexity 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 ...
