Questions & Step-by-Step Solutions

What is the height of a binary tree with only one node?
  • Step 1: Understand what a binary tree is. A binary tree is a structure that has nodes, where each node can have up to two children.
  • Step 2: Identify what is meant by 'one node'. This means there is only the root node and no children.
  • Step 3: Learn about the height of a binary tree. The height is defined as the number of edges on the longest path from the root to a leaf node.
  • Step 4: In a tree with only one node, there are no edges because there are no children. The root itself is also the leaf.
  • Step 5: Since there are no edges, the height of the tree is 0.
