โ“ Frequently Asked Questions

You should have completed AI Sketch or have equivalent knowledge of basic data structures (arrays, hash maps, strings). AI Chisel builds on those foundations with intermediate patterns.

Plan for 5โ€“6 hours. The intermediate patterns like two pointers, sliding window, and graph traversal require more practice time than the basics.

AI Chisel covers two pointers, sliding window, BFS/DFS graph traversal, tree traversals, stacks, queues, and monotonic patterns โ€” all tied to real AI and ML applications.

Yes, completely free. All programs on AI Educademy are open-source and available at no cost.

Absolutely. The patterns covered in AI Chisel appear frequently in medium-difficulty interview questions at major tech companies. Each lesson includes interview-style practice problems.

Graph traversal powers knowledge graphs and social network analysis. Tree structures underpin decision trees and random forests. Two pointers optimise data processing in ML pipelines. Every pattern connects to real AI applications.
