How to Get Started with Trees and Graphs in Data Structures?

I recently took a data structures exam and my best advice is to visualize how trees and graphs work rather than just coding them! For graphs, learn about vertices and edges, and the difference between directed and undirected graphs. Look into traversal methods like BFS and DFS, and algorithms like Dijkstra's for practice. Regarding trees, start with binary trees and binary search trees before moving on to AVL and Red-Black trees. A great resource I used was Jenny's YouTube Lectures! You've got a lot to learn, but no worries, it's totally doable! Good luck!

I recommend starting with trees first. Get comfortable with binary trees and their traversals before tackling graphs. Focusing on BFS and DFS patterns will really help you with most problems related to trees and graphs later on.

Trees are like fancy linked lists that branch out! Start with binary trees and then you can level up from there. For graphs, think of them like a weird social network where nodes are connected in various ways. Try LeetCode for some good tree-related problems, focusing on the easier ones to build up your skills.

Non-linear data structures can seem tricky, but they're manageable once you get the hang of recursion! Start with binary trees and learn about CRUD operations and traversal methods. Once you’re comfortable there, implementing graphs should feel more intuitive since graphs are essentially trees that can loop. Practice implementing graphs using different representations like adjacency lists and matrices.
