Solved Maximum Subarray (Medium) using Kadane’s algorithm to keep track of the max sum prefix in linear time, and Best Time to Buy and Sell Stock (Easy) by keeping track of the minimum price seen so far.
Deep-dived into the How to Deliver Answer system design interview framework: standardizing the step-by-step R → E → A → D → D (Requirements, Entities, APIs, High-Level Design, Deep Dive) model.
