What is the maximum number of children a node can have in a binary tree?

Answer:

Explanation:

In a binary tree, each node can have at most two children: a left child and a right child. This structure is what defines a binary tree, as the “binary” in the name refers to two possible child nodes.

Binary trees are used in various applications such as searching (binary search trees), sorting (heap sort), and representing hierarchical structures. The properties of binary trees make them a fundamental data structure in computer science.

A full binary tree is a binary tree in which each node has either zero or two children, while a complete binary tree is a binary tree in which all levels are fully filled except possibly the last level, which is filled from left to right.
