Consider a complete binary tree with 7 nodes. Let A denote the set of first 3 elements obtained by performing Breadth-First Search (BFS) starting from the root. Let B denote the set of first 3 elements obtained by performing Depth-First Search (DFS) starting from the root. The value of ∣A−B∣ is _____________.

What is the minimum number of nodes in a complete binary tree with depth 3?(A) 4(B) 5(C) 6(D) 7

"The search first begins from the root node and the first one of the child node's sub-tree is completely traversed. That is, first all the one-sided nodes are checked, and then the other sided nodes are checked."Which search algorithm is described in the above definition?1 pointThe Breadth First Search (BFS)The Depth First Search (DFS)The A* searchNone of the aboveOther:

n Depth First Search we examine _____.a)The starting node and then go deeper and deeperb)All of its children’s and then examine the root nodec)The neighbours and then the root noded)The root node and then traverse the neighbours

What is depth-first search (DFS)?Question 3Answera.A uniformed combinatorial search algorithm that expands nodes in a random orderb.A uniformed combinatorial search algorithm that expands nodes in order of their depthc.A uniformed combinatorial search algorithm that expands nodes in order of their distance from the rootd.A uniformed combinatorial search algorithm that expands nodes in order of their breadth

Compare and contrast depth-first search (DFS) and breadth-first search (BFS) algorithms in graph traversal. Discuss their applications and scenarios where one might be preferred over the other.
