Questions & Step-by-Step Solutions
In a binary tree, what does it mean if a node has both left and right children?
Step 1: Understand what a binary tree is. A binary tree is a data structure where each node can have at most two children.
Step 2: Identify the parts of a node. A node in a binary tree can have a left child, a right child, or both.
Step 3: Recognize what it means to have both children. If a node has both a left child and a right child, it means that it is not a leaf node and has two branches extending from it.
Step 4: Learn the terminology. A node with both left and right children is called a 'full node' in binary tree terminology.
