TopicsTrees & Graphs
Part of the AI Engineer Roadmap.
Summary
Hierarchical and networked data structures — core to interview problems and directly relevant to real structures like model architectures and knowledge graphs.
How to Learn This
- 1Practice DFS and BFS traversal on both trees and graphs until they're automatic.
- 2Solve tree problems: depth, balance, path sum, lowest common ancestor.
- 3Solve graph problems: connected components, shortest path, cycle detection.
