Solution: Single Element in a Sorted Array

Explore an efficient approach to find the single element in a sorted array where every other element appears twice. Understand how to apply modified binary search by adjusting pointers and indices to identify the unique number in O(log n) time 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 ...
