Algorithms and Data Structures in Action

Practical algorithms for real development work

Algorithms and Data Structures in Action is written for programmers who already know the basics and want a clearer, more useful way to think about performance. Rather than treating algorithms as abstract theory, Marcello La Rocca presents them as tools for solving concrete software problems: choosing the right structure, reducing bottlenecks, and making code behave better under pressure.

The opening chapters establish the book’s purpose plainly: data structures and algorithms belong together, and understanding both helps you reason more effectively about memory, speed, and trade-offs. From there, the book moves into a wide range of topics, including improved priority queues, treaps, Bloom filters, disjoint sets, skip lists, caching, nearest-neighbor search, k-d trees, similarity search, clustering, and graph-based optimization methods.

What the book emphasizes

• How common data structures can be improved or adapted for specific problems
• How to recognize when a more suitable structure can make code faster or leaner
• How algorithmic ideas translate into real-world engineering choices
• How to read pseudo-code and reason about implementations across languages

Built for developers who want more than a textbook

The tone is practical and explanatory, with optional deeper analysis for readers who want it. That makes this a strong fit for programmers, software engineers, and technically minded readers who already have some programming background and want to expand their toolkit without getting lost in purely academic presentation.

Helpful refreshers included

The appendices revisit essential groundwork such as pseudo-code, Big-O notation, recursion, graphs, and core data structures. That gives the book extra value as a reference when you need to revisit the basics before moving back into more advanced material.

If you want a structured, hands-on guide to algorithms and data structures that stays focused on actual problem solving, this title offers a thoughtful and wide-ranging path through the subject.
