Awesome LeetCode resources to learn Data Structures and Algorithms and prepare for Coding Interviews.

A link collection for interview prep: DSA concepts, LeetCode patterns, YouTube playlists, books, and problem sets. It's a jumping-off point, not a learning resource itself — almost everything here is an external link, mostly to the author's own AlgoMaster site and newsletter. Aimed at developers grinding for FAANG-style interviews.

The pattern implementations in six languages (Java, Python, Go, C#, C++, TypeScript) are the only original content and are genuinely useful as reference skeletons — clean, minimal, language-idiomatic. The organization by DSA topic and then by pattern is sensible and covers the standard interview canon without burying you. The curation of LeetCode discuss threads (sliding window template, backtracking guide) points to some of the best community writeups that are otherwise hard to find if you don't know they exist.

This is essentially a marketing funnel for AlgoMaster.io — the majority of links go to the author's own paid/freemium platform, newsletter, and YouTube channel, which makes it less of a community resource and more of an SEO play. The patterns directory only has 8 patterns across 6 languages and hasn't materially grown despite 17k stars; there's no Trie, no Union-Find, no DP template, no graph traversal implementation. No explanations exist in the repo itself — if the external links rot or go behind a paywall, this becomes a list of dead ends.
