Hierholzer Interview Questions

Reported as a Netflix interview question, this problem asks you to reconstruct a complete travel itinerary given a collection of individual flight segments. The primary goal is to assemble all provided tickets into a single, continuous journey, ensuring every segment is utilized exactly once. A specific starting point is mandated, and if multiple valid routes exist, the one that appears earliest alphabetically must be chosen. This task evaluates your ability to work with graph-like structures and apply traversal algorithms, potentially involving concepts related to Eulerian paths. The full problem description and a model solution are available with a subscription.
