DSA Pattern Study Kit

Recognize the pattern → apply the technique → implement with confidence. Seven patterns for the Senior SWE interview round.

Suggested path: read the Master Playbook’s Layer-1 sections to build the recognition reflex, work the deep-dives 01 → 07 (each has an interactive guide, a printable PDF, and a focused quiz), then take the 30-question master exam. Aim for 24/30 before live coding practice. Every page has hover/tap definitions for bold terms.
