Solution: Single Element in a Sorted Array

Explore a binary search technique tailored to find a single non-duplicate integer in a sorted array where every other number appears twice. Understand how to manipulate pointers and leverage index properties to efficiently solve the problem with logarithmic time complexity and constant space.

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 ...
