Give three valid BFS traversals (vertices in the order in which they are popped from the queue) starting from Vertex h. a b c d e f g h Provide three distinct BFS traversals below. One order per line. One vertex label per box. BFS traversal 1: h → Answer 1 Question 1[input] → Answer 2 Question 1[input] → Answer 3 Question 1[input] → Answer 4 Question 1[input] → Answer 5 Question 1[input] → Answer 6 Question 1[input] → Answer 7 Question 1[input] BFS traversal 2: h → Answer 8 Question 1[input] → Answer 9 Question 1[input] → Answer 10 Question 1[input] → Answer 11 Question 1[input] → Answer 12 Question 1[input] → Answer 13 Question 1[input] → Answer 14 Question 1[input] BFS traversal 3: h → Answer 15 Question 1[input] → Answer 16 Question 1[input] → Answer 17 Question 1[input] → Answer 18 Question 1[input] → Answer 19 Question 1[input] → Answer 20 Question 1[input] → Answer 21 Question 1[input] In case you do not recall how to traverse a graph with BFS, we provide an algorithm below, as given in the course notes.
