Implement DFS for connected components

Q: Implement DFS for connected components

This question evaluates a candidate's ability to implement depth-first search for connected components, covering both recursive and iterative implementations while testing understanding of stack-safety, time and space complexity, and edge-case testing.

Q: How do I approach Coding & Algorithms interview questions?

Coding & Algorithms questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master coding & algorithms interviews.

Question

Given an undirected graph with n nodes (1 ≤ n ≤ 200, 000) and an edge list, implement depth-first search to compute (a) the number of connected components and (b) the size of the largest component; provide both recursive and iterative implementations; discuss stack-safety for large graphs, time and space complexity, and how you would test edge cases.
