Cluster: Topics

Core Computer Science Concept Topics

Four foundational CS concepts, one per page. Big-O notation with a cross-language benchmark from n=10 through n=10000, recursion with per-language max depth limits, pointers with a real GDB session and Valgrind output, concurrency with a worked deadlock walkthrough. Each topic covers the failure modes graders deduct points for on CS161, CS61B, CS50, and CMU 15-213 problem sets.

Why the Topics Cluster

Concept-first pages cut across languages and courses

A student stuck on recursion in Java is stuck on recursion in Python the next week. The concept does not change with the language. CSHH built this cluster so foundational ideas live on their own pages, decomposed with real benchmarks, real GDB sessions, and the named failure modes graders deduct points for, instead of repeated as a brief paragraph on every language and course page.
