DIY: Single Element in a Sorted Array

Explore how to find the single non-duplicate element in a sorted array using an O(log n) time complexity approach with constant space. This lesson helps you implement an efficient function suited for coding interviews focused on algorithmic problem solving with sorted data.

Problem statement

In this problem, you are given an array of sorted integers in which all of the integers will appear twice, except one. Your task is to find that single integer, which will appear only once.

Please note that your solution will have a time complexity of ...
