Which of the following is NOT a property of a binary search tree?

Which of the following is NOT a property of a binary search tree?

Step 1: Understand what a binary search tree (BST) is. A BST is a type of data structure that organizes data in a way that makes searching efficient.
Step 2: Know the properties of a binary search tree. In a BST, for any given node, all values in the left subtree are less than the node's value, and all values in the right subtree are greater.
Step 3: Recognize that nodes in a BST do not have to be at the same level. This means that some nodes can be deeper in the tree than others.
Step 4: Identify the question's focus. It asks which statement is NOT a property of a BST.
Step 5: Conclude that the fact that all nodes are not required to be at the same level is indeed NOT a property of a BST, as it is a characteristic of how trees can be structured.
