Hello Algo is a free, open-source illustrated book that teaches data structures and algorithms from scratch using animated diagrams and one-click runnable code.Is this a coding library or a book to read?It is a tutorial book (readable online or via this repo), not a software library — the code snippets are worked examples you run to understand each algorithm, not a package you import into a project.
It is a tutorial book (readable online or via this repo), not a software library — the code snippets are worked examples you run to understand each algorithm, not a package you import into a project.How do I start reading and running the examples?Work through the chapters in order starting from the basics; each chapter's source code is 'one-click runnable' so you can execute it directly to see how the data structure or algorithm behaves.
