Apple JavaAlgorithms Archify + AlgoSim

Optimized for Apple Technical Screen (Oct 22) • Archify Diagrams & Live Simulation

Target Interview: Oct 22, 2026 • 3-Day Critical Sprint

High-Yield Archify Architecture Diagrams

Every critical Apple interview problem is modeled into an interactive Archify architecture & data-flow diagram. Visually memorize pointer rewiring, concurrency lock boundaries, CPU schedule frames, and dependency DAG resolution.

📅 DAY 1 (OCT 19-20) Critical #1

Data Structure Design & Concurrency

Master: LRU Cache (#146), Hit Counter (#362), Bounded Blocking Queue. Explain why ReadWriteLock fails for get().

📅 DAY 2 (OCT 20-21) Critical #2

Recent 30D Apple High-Freq & Graph

Memorize geometry: Task Scheduler (#621), Is Graph Bipartite? (#785), Course Schedule (#207), TimeMap (#981).

📅 DAY 3 (OCT 21-22) Critical #3

Fast Screening, Pointers & Intervals

Rapid reflex: Two Sum (#1), 3Sum (#15), Merge Intervals (#56), Reverse Linked List (#206). Zero boundary bugs.
