Definition:Binary Tree
Separate out the definitions of left-hand branch and right-hand branch.
Until this has been finished, please leave {{refactor}} in the code.
New contributors: Refactoring is a task which is expected to be undertaken by experienced editors only. Because of the underlying complexity of the work needed, it is recommended that you do not embark on a refactoring task until you have become familiar with the structural nature of pages of $\mathsf{Pr} \infty \mathsf{fWiki}$.
Definition
A binary tree is a rooted tree which has at most two branches at any node.
That is, every node in a binary tree has degree of at most $3$ (one for the parent, two for the children).
The branches at any particular node are frequently called the left-hand branch and the right-hand branch, and a distinction is made between them.
Applications
Binary trees are frequently used in computer science to store data in an efficiently searchable fashion.
