Real-world uses of tree and graph structures are everywhere! Let's look at some examples.

Trees

1. File Systems:

   • Picture your computer's storage. It often looks like a tree. Folders are like branches, and files are the leaves. This setup makes it easy to find what you need.

2. Family Trees:

   • Family trees show how people are related. Each person is a dot, and lines connect them to show relationships. This helps us see our family history clearly.

Graphs

1. Social Networks:

   • Think about apps like Facebook or Instagram. Each user is a dot, and friendships are the lines that connect them. This helps us see how friends are linked.

2. Navigation Maps:

   • Online map services like Google Maps use graphs, too. Locations are dots, and roads are the lines between them. This helps us find the shortest path to places.

Traversals

To look at or manage data in these structures, we use something called traversals. For example:

• In trees, we can use different ways like pre-order, in-order, or post-order to access data in various sequences.
• In graphs, we can use depth-first search (DFS) or breadth-first search (BFS) to find our way through the dots.

Learning about trees and graphs is important. It helps us interact with and manage data in our everyday digital lives!
