What is it?

This repository provides Go solutions to LeetCode problems, organized by problem number with a directory that links each problem to its solution folder. The code follows the Google Golang Style Guide, and the solutions are paired with a companion e-book called LeetCode Cookbook that is available for online reading as a PWA and as an offline PDF.

Beyond the problem solutions, the project includes overview tables covering data structures such as heaps, tries, and trees, and algorithm families such as sorting, dynamic programming, graph theory, and number theory. These tables serve as a reference map of topics for learners working through algorithm material.

The author notes that the solutions aim for full test coverage and runtime results at the top of LeetCode's rankings. The repository is useful for developers preparing for coding interviews who want to compare their Go solutions against worked examples.

Key features

  • 01Go solutions for LeetCode problems, indexed by problem number and difficulty.
