Solution: Single Element in a Sorted Array

Understand how to apply a modified binary search to identify the one unique element in a sorted array where all others appear twice. Learn the step-by-step approach to adjust pointers and indices, ensuring an optimal O(log n) time complexity and constant space usage.

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 ...
