NeetCode 50‑problem roadmap
Sam Ivere (NeetCode) advises focusing on 50 pattern‑based LeetCode problems across arrays, strings, hashmaps and two‑pointers to cover roughly 80% of interview questions. The roadmap is meant to compress prep time while maximizing pattern recognition. (x.com)
NeetCode’s public practice library currently aggregates about 954 curated problems and lists Arrays: 310, String: 131, Hash Table: 122 and Two Pointers: 61 — the same topic buckets cited in the 50‑problem shorthand are visible on the NeetCode practice page. (neetcode.io) NeetCode formalizes pattern‑based training with named courses and topic playlists; its Two Pointers course explicitly recommends problems such as Valid Palindrome, Two Sum II, Container With Most Water and Trapping Rain Water as canonical exercises. (neetcode.io) The NeetCode 150 and NeetCode 250 lists are positioned as larger, official roadmaps that expand the “must‑know” set to 150 and 250 problems respectively, showing NeetCode’s curated path from a compact study set to broader coverage. (neetcode.io 1) (neetcode.io 2) Community adoption is extensive: multiple open‑source GitHub repositories mirror the NeetCode roadmap and solutions (example: a community NeetCode roadmap repo with 150+ problems and many forks), indicating the 50/150/250 lists are treated as standardized study curricula. (github.com) Industry writeups and teaching platforms describe NeetCode’s method as a pattern‑first approach that expanded the older “Blind 75” model into a larger NeetCode 150 standard, framing compact lists as entry points rather than complete prep suites. (educative.io) (dev.to) Independent study guides and blogs that publish “top 50” problem collections back the community heuristic that a focused set of ~50 recurrent pattern problems covers a large fraction of interview scenarios, a line of reasoning echoed in the social post that prompted this briefing.
