Rather than running your code against 100 different test cases and failing you if you miss 1, is there a platform that can use AI to tell you if you have the correct approach that covers the general case and then a couple of the more common edge cases? I feel like that would more useful and more in line with a standard white board interview.

LeetHub isn't syncing with the new LeetCode UI. Any suggestions for alternatives that smoothly push LeetCode solutions to GitHub?
i have tried LeetHub 2.0 but after the latest UI update which is not support in the current version of leethub.
if you know any other similar extensionw which is still working please comment down.

What are the good alternatives to LC in terms of interview preparation with the same effectiveness but not so overwhelming?

I found hack2hire, but they seem to have little number of problems in total... what else? codility?

Hi R

I was looking into LeetCode and it seems the solutions they have there are from “the community”, which has no guarantee that the answers are actually the best solution or even that they are correct.

I’m looking for an alternative platform that also has good challenges, ones that are actually similar to real interview problemas, but that have the “official” resolution explanation, considering the best answer to the problem.

Please, would anyone have any recommendations?

Thank you

So far I haven’t used a service like leet code. But from what I read that even the simple problems are fairly difficult. My question is if there is an alternative I could start out with that isn’t as difficult to start out with.

I’m not opposed to Leetcode, But don’t want to start out as frustrated.

I want to practice and strengthen my programming/problem solving skills. I’ve heard about Leetcode and how many people recommend it, but it’s not free. Does anyone know any free alternatives that I can try out?

I read that Websites like leetcode aren't representative of the type of problems that one will face in a day to day work environment. What would be a more useful way to practice coding and problem solving then?

Hi, I'm looking for an app or site like sololearn but only for algorithms and data structures.i was thinking about solving leetcodes but I feel like a dumb ass since I mix up algorithms and can't code that well since I don't practice that much. I'd be grateful for your advices.

In school, I learned math best by doing TONS of problems. I am looking for good resources that will allow me to do the same thing as I practice DSA. The ideal platform would have problems that are easier than/about the same as Leetcode easys and can be filtered by topic.

So far, the only thing I have found is GeeksforGeeks. It lets me filter by Basic and also choose different data structures or techniques to filter by.

Any other suggestions?

I am a Software Engineer in the industry for 7 years! Unlike the average individual, I actually like leetcode even though it has no correlation with job performance. It just satisfies my itch of solving problems and having a fast feedback loop: sort of like crossword or sudoku or math puzzles pr

I also like programming languages and like learning exotic languages. Are there sites that are more expansive than leetcode: test file io, or some regex parsing, or date time math or interacting with csv, json, concurrency or dealing with binary data. These will help me learn the capabilities of a new language much faster than just reading a book on the language.

I usually do projects but was wondering if there was something more expansive than leetcode with an autograder that tests some of the things I mentioned. This will satisfy the puzzle itch

So I am a career switcher, trying to find a Junior SWE position in this god awful market, and am trying to prepare for possible technical interviews. I have found this task rather daunting because the only prominent services for interview practice seem to be Hackerrank and Leetcode. These two services are god awful because every exercise is made unreasonably difficult; if a question doesnt require some advanced mathmatical or scientific background to even understand the problem statement, it requires you to use some ridiculously roundabout method to solve the problem, and will mark the answer wrong if you use a simpler, more practical method. I know from experience completing technical interviews that decent employers dont employ questions like these when interviewing Juniors, and I know from my experience interning on a development team that the ability to solve brain teaser problems is irrelevant to a Junior SWE's Job.

The kinds of problems I want to practice would be something like "create a program that checks if a string is a palindrome" or "create a program that checks which items in an array of strings are represented more than once" (these are actual questions I was given during a technical interview for a Junior SWE position). Can anyone reccomend a book or website that focuses on problems at or around this level?

is there a website similar to leetcode but with free answers to all the programming problems ?

If somebody showed you their github project and it was impressive, wouldnt that be better than solving x number of leetcode questions?

I have been facing trouble with leet code problems and it's frustrating me. I studied and practiced Python from books and online tutorials and couple of my friends suggested me to try LeetCode but now I feel like I'm trying to jump on top of the building without taking the stairs. Please suggests me as to how to progress? Thanks in adv.

Do you guys maintain a git repository for the leetcode solves? Do you go back to the repository and revise? What is the best way to maintain that leetcode repository to revise?

I recently tried both Neetcode (the free video content) and the Leetcode Crash Course. While Neetcode is free and popular, I ended up feeling that “free” wasn’t necessarily better. Here’s what stood out:

What bothered me about Neetcode:

• Some explanations felt unclear or contradictory.

• The code in the videos often didn’t match the solutions on the site.

• They have a paid course ($119/year or $497 lifetime), which includes foundational templates. If you don’t get those templates, you might just end up memorizing solutions without fully understanding them.

Why I switched to Leetcode Crash Course:

• It’s a one-time payment (about $90).

• They include templates for all main algorithms, so you can actually practice applying them (not just rote memorization).

• There are concise notes that help you review quickly—no need to rewatch hours of videos when you’re crunched for time.

• It uses the actual Leetcode platform, so you’re practicing in the same environment you’ll be using for your further practice.

In the end, I prefer the structure and clarity of the Leetcode Crash Course. It might not be free, but it made my interview prep more straightforward. That said, everyone’s learning style is different—this is just how things panned out for me.

Let's see one example using Leetcode 542. You can have a feeling of his style:

He only used less than 4 minutes to explain the algorithm to the question and code along with explanation.

Almost all parts of his codes are from his templates (valid function is his template to verify the boundary, from Line 14 to Line 18 are his template to construct the graph based on matrix, from Line 21 are the BFS template). So memorize these templates ahead and quickly write them in the solution can save a lot of time and brain energy. His codes are elegant. You can see his style from this example.

If you think his method to use templates to solve Leetcode is helpful or you're not comfortable with this question, then this course has the some values for you.

I'm glad leetcode style questions are prominent. If you haven't gone to a top school and you have no/little experience there'd be no other way to get into top tech companies like Google and Facebook. Leetcode really levels the playing field in that respect. There's still the issue of getting past the resume review stage and getting to the interview. Once you're there though it's all about your data structures and algorithms knowledge.

It's sure benefitted me at least. I graduated from a no-name university in the middle east at the end of 2016 with a 2.6 GPA. Without the culture of asking leetcode style questions I probably would never have gotten into Facebook or at Amazon where i currently am.

I think that without algorithm questions, hire/no-hire decisions would give more weight where you've worked, what schools you went to, how well you build rapport with the interviewer etc. similar to some other industries (like law I think). In tech those things only matter for getting to the interview.

Basically the current tech interview culture makes it easy for anyone to break it's helped break into the top tech companies (FANG/big-4/whatever) and I think most engineers with enough time on their hands can probably do so if they want to.

I started with Edabit yesterday, but my trial is over, so i am looking for a new website to solve problems for free. I just started, so to pay is not an option for me right now :)

I'm only a freshman and started leetcoding and recently past 100 questions. I will keep doing these for a long time but I think there might be some better stuff to do rather than grinding for 4 years everyday. My grades are good
