Key binary-search problems listed
A curated list of essential binary‑search LeetCode problems — from First/Last Position to Rotated Sorted Array variants, Peak Element and Sqrt(x) — is getting circulated as the must‑practice set for interview filters. The thread frames these problems as pattern anchors that unlock many medium-level questions (x.com).
The circulated checklist names concrete LeetCode entries by number and title — e.g., 34 (Find First and Last Position), 33 (Search in Rotated Sorted Array), 153/154 (Find Minimum in Rotated Sorted Array / its variant), 162 (Find Peak Element), 69 (Sqrt(x)), 540 (Single Element in a Sorted Array), 704 (Binary Search), 278 (First Bad Version) and 74 (Search a 2D Matrix). (neetcode.io) (github.com/BrandonBian/leetcode) NeetCode’s curated binary‑search collection lists roughly 50 problems under the “Binary Search” tag, with individual entries for Sqrt(x), Find Peak Element and Search in Rotated Sorted Array. (neetcode.io) (leetcode.com/problem-list/ab200csr/) Data aggregators show interview frequency for specific items: DSAPrep reports Search in Rotated Sorted Array has appeared in 68 interview instances spanning 26 companies. (dsaprep.dev) LeetCode problem pages quantify usage — Find Peak Element shows about 2.35M accepted submissions and a roughly 46.8% acceptance rate on its problem page, illustrating how often candidates attempt that exact prompt. (leetcode.com/problems/find-peak-element/) The thread has been paired in many reposts with practical study material: a public GitHub “Binary Search” cheat‑sheet and AlgoMonster/NeetCode walkthroughs that provide templates, multi‑language code and step‑by‑step proofs for the same problem set. (github.com/daily-coding-problem/leetcode-study-plans) (algo.monster) Platform inventories and community lists underline scale — TutorialsPoint aggregates 309 binary‑search tagged problems across difficulties, and a LeetCode Discuss post titled “20 Binary Search Problems To Revise Before Interviews” maps several of these exact problems to interviews at Amazon, Microsoft, Meta, Apple and Google.
