Maximum Subarray: Kadane's Algorithm

Targeted in FAANG & Tech OA:GoogleAmazonMicrosoft
Real-World Engineering Context
Used in computer vision (finding highest-contrast regions in an image) and genomic sequence alignment to locate protein coding regions.
Given an integer array `nums`, find the subarray with the largest sum, and return its sum.
