In a tree, which traversal method is equivalent to a level order traversal?
Step 1: Understand what a tree is. A tree is a data structure that consists of nodes connected by edges, with a single node called the root at the top.
Step 2: Learn about tree traversal methods. Traversal means visiting all the nodes in a tree in a specific order.
Step 3: Identify the level order traversal method. Level order traversal visits all nodes at the present depth level before moving on to nodes at the next depth level.
Step 4: Recognize that level order traversal is also known as Breadth-First Search (BFS). BFS explores all neighbors at the present depth prior to moving on to nodes at the next depth level.
Step 5: Conclude that level order traversal and BFS are equivalent because they both visit nodes level by level.
