Hi everyone,

I’ve just finished writing a 1600-page data structures book that contains 130 fully original academic-style problems, each with complete solutions, proofs, amortized analysis, diagrams, and detailed explanations.

The book is designed for:

university-level advanced data structures learning

self-study for engineers

technical interview preparation (many problems are structured like interview challenges)

deep understanding of heaps, trees, union-find, RMQ, hashing, string structures, and more

I also included two new data structures that I designed myself — the Layered Summary Heap (LSH) and the Triple-L Heap — with step-by-step explanations and use cases.

I would appreciate feedback from the Hacker News community on:

clarity and structure

difficulty level

and whether such a long-form problem book is useful for interviews and self-study
