Is LeetCode good for practice?

Definitely Leetcode is a great resource to prepare technical interview. It has quite a few very interesting and helpful coding questions that can help you be better prepared for an interview.

How do I get better at solving LeetCode problems?

The strategy

1. Go to a quiet location.
2. Pick a question.
3. Set a timer for 25 minutes.
4. Allocate the first 5 minutes to understand the problem and ask/answer clarifying questions to yourself.
5. Spend the next 20 minutes solving the problem on paper & pen/pencil (until timer rings).

Can a beginner use LeetCode?

Many of those problems are also available on LeetCode, so you can actually use LeetCode as a complementary tool alongside the book. I would consider the book to be fairly entry-level, so if you’re new to technical interviews, I’d recommend starting by going through the book, even before doing LeetCode full-time.

Is Leetcode better than interview bit?

Interview questions and experiences also help to understand the interview process better. Two contests per week are also there in Leetcode. The Community of Leetcode is way better than the InterviewBit one.

Is Leetcode good for Google interview?

For interview preparation, the top sites are Leetcode, GeeksForGeeks and Interview Bit. Leetcode beats the other two sites handsdown. Leetcode has everything that a good site should, amazing list of questions, good editorials, really good testcases as well as a community(best thing).

How long should I spend on a leetcode problem?

In fact, I would recommend spending much less: just one hour per problem, maybe two hours if you’re still making progress after an hour, or if you have several hours per day available to practice LeetCode. Once you hit this time limit, start looking for hints in the problem or the discussion boards. Why stop after an hour or two?

How to prepare for leetcoding?

Before you start Leetcoding, you need to study/brush up a list of important topics. If you don’t, you’ll end up wasting your time. Remember the two following rules: Don’t spend too much time on the prep work. Don’t spend too little time on the prep work. If you spend too much time studying, you’ll never get to solve Leetcode/CTCI problems.

How do I write a model solution for leetcode?

The LeetCode online judge only cares about the code, but a model solution is more than just code. To understand and remember a solution, explain it to an interviewer, and apply it to similar problems, your model solution needs a few parts. I use these sections when writing a model solution: Restatement of the problem description.

What’s the difference between traditional spaced repetition and leetcode?

Traditional spaced repetition uses flashcards (paper or electronic) that have a prompt on one side and an answer on the other. For LeetCode, we’re not trying to memorize lines of code. But it’s still important to have a specific goal for what it means to learn a problem, besides just getting an accepted submission.
