Solution: Single Element in a Sorted Array

Understand how to locate the single element in a sorted array where all others appear twice using a modified binary search approach. Learn to adjust pointers based on pair patterns to achieve optimal time and space complexity while solving this common coding interview problem.

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 ...
