Collections - leetcode-py

Collections are curated problem lists (Grind 75, Blind 75, the NeetCode roadmaps) encoded as tags. Every collection is a tag you can filter, list, and bulk-generate with. Membership is defined in tags.json5 inside the JSON resources; lcpy reads it for -t filters.

The collections

Collection	What it gives you
`grind-75`	The essential 75 from Tech Interview Handbook, ordered by a study plan
`grind`	Extended Grind; superset of Grind 75 with more problems
`blind-75`	The classic curated list that started the trend
`neetcode-150`	Comprehensive NeetCode coverage by topic
`neetcode-250`	The full NeetCode roadmap; coverage still growing
`algo-master-75`	Algorithmic mastery set curated in this repo, 75 problems

Current problem counts live on the Catalog pages, which are generated straight from the templates and never go stale.

Preview before you generate

lcpy list -t grind-75              # every problem in the collection
lcpy list -t neetcode-250 -d Hard  # narrow to one difficulty

Generate a whole collection

lcpy gen -t grind-75        # all of Grind 75 into ./
lcpy gen -t blind-75 -o leetcode
lcpy gen -t grind-75 -d Easy   # just the Easy problems

Bulk generation prints one Generated problem: line per problem and creates each directory with the standard six files.

Bulk generation output for all Grind 75 problems

Folder structure with all generated problem directories

Picking a collection

Short on time: grind-75. Want the classic list everyone references: blind-75. Preparing by topic with video explanations: neetcode-150. The right collection is the one you will finish; every one of them generates the same high-quality problem directories.
