1.	Time Complexity of DFS is? (V – number of vertices, E – number of edges)(a) O(V + E)(b) O(V)(c) O(E)(d) O(V*E)The question was asked in an interview for job.This question is from Depth First Search topic in chapter Graph Search of Data Structures & Algorithms II
Answer» The correct choice is (a) O(V + E) To EXPLAIN: The DEPTH First Search EXPLORES every node once and every edge once (in worst case), so it’s time complexity is O(V + E).
