DSA questions based on trees, DSU, sliding windows, and quick sort
AI-Expanded — inferred from the question title, not from the original candidate report
Given a forest of trees represented as an array of edges, use a Disjoint Set Union (DSU) to group connected components and identify the size of each tree. Once the components are identified, extract the root values into a list, sort them using the Quick Sort algorithm, and finally apply a sliding window approach to find the contiguous subarray of sorted roots that has a sum closest to a target value K.
Context & Summary
Technical round focused on Data Structures and Algorithms, including topics like trees, DSU, sliding windows, and quick sort. Followed by a brief discussion about the candidate's projects.
