Questions & Step-by-Step Solutions
Which of the following algorithms can be used to find the height of a binary tree?
Step 1: Understand what a binary tree is. A binary tree is a structure where each node has at most two children, called the left child and the right child.
Step 2: Know what the height of a binary tree means. The height is the number of edges on the longest path from the root node to a leaf node.
Step 3: Learn about depth-first search (DFS). DFS explores as far down a branch as possible before backtracking. It can be used to traverse the tree and calculate the height.
Step 4: Learn about breadth-first search (BFS). BFS explores all the nodes at the present depth level before moving on to the nodes at the next depth level. It can also be used to find the height of the tree.
Step 5: Realize that both DFS and BFS can be implemented to calculate the height of the binary tree by counting the levels of nodes.
