LeetCode Study Lists: Blind 75, NeetCode 150 and Three More

A study list is somebody's answer to "if you only have time for a hundred problems, which hundred?". That judgement is the whole value, and it is why these lists cannot be derived — no query over the problem set reproduces them.

None of the five below originate here. We reproduce each one by problem number, in the order the list itself uses, and link every entry to its page in this library. Between them the five name 525 entries; 525 resolve to a problem in this library, covering 285 distinct problems once the overlap between the lists is removed. Nothing is padded to make a title's number come out right — each page states what it actually holds.

Blind 7575 problems · 19 Easy · 49 Medium · 7 HardThe Blind 75: a 75-problem list assembled from the patterns that keep reappearing in technical interviews, grouped by topic. Every entry links to a Python solution with complexity analysis.NeetCode 150150 problems · 28 Easy · 101 Medium · 21 HardThe NeetCode 150: an expansion of the Blind 75 into eighteen topic groups, from arrays and hashing through advanced graphs and two-dimensional dynamic programming.Grind 7575 problems · 23 Easy · 43 Medium · 9 HardThe Grind 75: the Blind 75 reworked into a week-by-week schedule that starts with the easiest high-yield problems and ends on the hard ones. Ordered for study, not by topic.LeetCode 7575 problems · 22 Easy · 53 Medium · 0 HardLeetCode 75: the official study plan, seventy-five problems across twenty-two topic groups from array and string work up to monotonic stacks. Skewed easier than the Blind 75 and better as a first pass.Top Interview 150150 problems · 40 Easy · 92 Medium · 18 HardTop Interview 150: the official interview-preparation list, a hundred and fifty problems covering every data structure and technique a technical screen is likely to reach for.

Stealth Interview is a desktop app for macOS and Windows. It reads the coding problem off your screen, returns a working solution with a step-by-step explanation and its time and space complexity, and transcribes what the interviewer is saying — while staying invisible to screen sharing.
