Who else use the trees
Answers
- When you are dealing with a huge amount of data that spans several rows or columns, you may want the headers to remain constant (frozen) while you scroll through the data so that you can see the identifying names of the rows/columns is called Freezing of rows and columns.
the Woodcutters specially !
pls mention ur Ques. clearly.
Answer:
When you first learn to code, it’s common to learn arrays as the “main data structure.”
Eventually, you will learn about hash tables too. If you are pursuing a Computer Science degree, you have to take a class on data structure. You will also learn about linked lists, queues, and stacks. Those data structures are called “linear” data structures because they all have a logical start and a logical end.
When we start learning about trees and graphs, it can get really confusing. We don’t store data in a linear way. Both data structures store data in a specific way.
This post is to help you better understand the Tree Data Structure and to clarify any confusion you may have about it.
In this article, we will learn:

Examples of trees
Its terminology and how it works

Let’s start this learning journey. :)
Definition
When starting out programming, it is common to understand better the linear data structures than data structures like trees and graphs.
Trees are well-known as a non-linear data structure. They don’t store data in a linear way. They organize data hierarchically.
Let’s dive into real life examples!
What do I mean when I say in a hierarchical way?
Imagine a family tree with relationships from all generation: grandparents, parents, children, siblings, etc. We commonly organize family trees hierarchically.
My family tree
The above drawing is is my family tree. Tossico, Akikazu, Hitomi, and Takemi are my grandparents.
Toshiaki and Juliana are my parents.
TK, Yuji, Bruno, and Kaio are the children of my parents (me and my brothers).
An organization’s structure is another example of a hierarchy.
A company’s structure is an example of a hierarchy
In HTML, the Document Object Model (DOM) works as a tree.
Document Object Model (DOM)
The HTML tag contains other tags. We have a head tag and a body tag. Those tags contains specific elements. The head tag has meta and title tags. The body tag has elements that show in the user interface, for example, h1, a, li, etc.
A technical definition
A tree is a collection of entities called nodes. Nodes are connected by edges. Each node contains a value or data, and it may or may not have a child node
