Best Tips for Getting Started With Best coding challenges Websites
Most people do not know how to start and make full use of all these websites. So, here are some of the most useful tips that you can follow:
- If you are a beginner in competitive coding then don’t jump straight into the competition. First of all, go to PROBLEMSET option and set the difficulty level to 800-1000. After that, all the problems of that difficulty level will be exposed to you, and start solving problems from there. Then solve at least 30-40 problems to get familiar with the type of questions and the platform. Once you are familiar with those problems, you can start with competitions.
- Try to give all the contests (there are 2-3 contests every week). Initially, it is possible that you may be able to solve 1 or 2 problems in competitions, or it may be that you may not be able to solve even a single problem, but you should not lose hope and keep practicing problems.
- After each contest, try to solve the remaining problems of the contest. This is really important as you will be able to learn many new concepts and tricks from it. For those who do not know, up-solving means solving the remaining problems of the competition which you were not able to solve during the competition.
- After solving any practice problem, see other users’ solutions, and also you will learn different and easy ways from those solutions which will definitely help you with further problems.
- As soon as you are confident in solving questions of a particular difficulty level, keep increasing the difficulty level of the questions.
- Lastly, be consistent and keep practicing.
