Questions & Step-by-Step Solutions
Which of the following is NOT a property of a binary tree?
Step 1: Understand what a binary tree is. A binary tree is a data structure where each node has at most two children, referred to as the left child and the right child.
Step 2: Recognize that there are different types of binary trees. One type is a binary search tree (BST), which has specific properties.
Step 3: Identify the properties of a binary search tree. In a BST, the left child of a node is always less than the parent node, and the right child is always greater.
Step 4: Understand that not all binary trees follow the rules of a binary search tree. A regular binary tree does not have to maintain the left child being less than the parent.
Step 5: Conclude that the property of the left child being less than the parent is NOT a property of all binary trees, but only of binary search trees.
