Solution: Single Element in a Sorted Array
Explore how to efficiently find the single non-duplicate element in a sorted array where every other element appears twice. Learn to apply a modified binary search approach that leverages index parity to reduce search space, resulting in logarithmic time and constant space complexities. This lesson guides you through the step-by-step reasoning and implementation, helping you master this common interview problem pattern.
