1.	In Depth First Search, how many times a node is visited?(a) Once(b) Twice(c) Equivalent to number of indegree of the node(d) ThriceThis question was addressed to me during an interview for a job.My doubt is from Depth First Search in division Graph Search of Data Structures & Algorithms II
Answer» Correct option is (c) Equivalent to number of INDEGREE of the node To EXPLAIN: In DEPTH First Search, we have to see WHETHER the node is visited or not by it’s ancestor. If it is visited, we won’t LET it enter it in the stack.
