🌳 Parent and Child in Tree | Tree Data Structure Explained in English | DSA for Beginners | Skills101

Welcome to this complete and beginner-friendly explanation of Parent and Child Nodes in Tree (DSA).
If you are learning Data Structures and Algorithms, preparing for placements, or trying to understand the fundamentals of Tree Data Structure, then this video will give you absolute clarity.

Understanding Parent and Child in a Tree is extremely important because every concept in Trees — Binary Trees, BST, AVL Tree, Heap, Trie, B-Tree, Segment Tree — is built on this relationship.
This video breaks down the concepts in very simple language, using diagrams and real-life examples so that even a beginner can understand it clearly.

🌳 What Are Parent and Child in a Tree (DSA)?

A Tree is a hierarchical, non-linear data structure made of nodes.
Every node may be connected to multiple other nodes.

The relationship between nodes forms the basis of the Tree, and two of the most important terms are:

Parent Node

Child Node

Let’s understand both in detail.

✔ What is a Parent Node?

A Parent Node is a node that has one or more child nodes connected directly below it.
It serves as a predecessor in the tree structure.

Simple definition:
👉 A Parent is the node directly above another node.

Example:
If A connects to B, then
A = Parent
B = Child

Parent is responsible for holding references/pointers to its child nodes.

✔ What is a Child Node?

A Child Node is a node that descends from another node.
It is directly connected below the parent.

Simple definition:
👉 A Child is the node directly below another node.

Example:
If A connects to B and C:
A = Parent
B = Child
C = Child

A node may have:

0 children (Leaf Node)

1 child

2 children (Binary Tree)

More than 2 children (General Tree)

🌳 Parent–Child Relationship in a Tree

This relationship forms the basis of the entire Tree structure.
Each node except the root has exactly one parent.
But a parent can have multiple children.

✔ One Parent → Multiple Children

Example:

A
/ | \
B C D


A is the parent of B, C, and D.

✔ Every Child Has Only One Parent

B’s parent is A
C’s parent is A
D’s parent is A

Only root node has no parent.

🌱 Why Parent and Child Concept Is Important in DSA?

Understanding parent–child structure helps you master:

✔ Tree Traversals

Preorder: Root → Left → Right

Inorder: Left → Root → Right

Postorder: Left → Right → Root

🎯 Coding Interview Questions Related to Parent and Child
✔ What is a parent in a Tree data structure?
✔ What is a child node in a Tree?
✔ Can a node have multiple parents?

(No — except root, each node has one parent)

✔ What is the difference between parent and child?
✔ Can a parent be a child of another node?

(Yes — except root)

✔ How many children can a parent have?

(Depends on the type of tree)

✔ Why does a Tree grow downward?

Hierarchical structure representation

These are common interview questions you must master.
