How do you make DFS Cycle Detection (Directed Graph) safer under partial failure?

Answers use simple, clear English.

Quick interview answer

Harden DFS Cycle Detection (Directed Graph) with timeouts, retries with jitter, isolation, and graceful degradation. Mitigate first, then root-cause. Check symptoms against: Using two-color visited only (misses cross edges in undirected); forgetting disconnected components..

Detailed answer

Resilience for DFS Cycle Detection (Directed Graph) under partial failure: • Timeouts + budgets on every dependency call • Retries only when idempotent, with jitter/backoff • Isolation: bulkheads/queues so one failure does not cascade • Degradation: serve stale/cached/limited mode when needed Practices: Loop all nodes as DFS roots; explain gray = active recursion path. Parent context: Mitigate first, then root-cause. Check symptoms against: Using two-color visited only (misses cross edges in undirected); forgetting disconnected components..

Full explanation

Partial failure is the default in distributed systems — show how DFS Cycle Detection (Directed Graph) stays useful anyway. Three-color DFS: white=unvisited, gray=in current stack, black=done. Back edge to gray node ⇒ cycle. Works for dependency graphs and course prerequisites.
