Audio N/AQuick interview answer
Pros: O(V+E); distinguishes directed vs undirected cycle logic. Cons: Recursive DFS risks stack overflow on huge graphs; use iterative + explicit stack.
Detailed answer
Trade-offs for DFS Cycle Detection (Directed Graph): Pros: O(V+E); distinguishes directed vs undirected cycle logic. Cons: Recursive DFS risks stack overflow on huge graphs; use iterative + explicit stack. Decision rule: choose DFS Cycle Detection (Directed Graph) when the benefits outweigh operational cost for your SLO. Parent context: Mitigate first, then root-cause. Check symptoms against: Using two-color visited only (misses cross edges in undirected); forgetting disconnected components..
