Hello 👋 Beautiful People out there, Hope you find yourself well and healthy.

I'm bringing my new article which is focused on the A, B, C's of Competitive Coding and to bring the top 10 competitive coding platforms where you can learn, practice, master and compete with others based on your coding skills.

Note : This article is going to be long but you will enjoy reading every bit of it.

Many of you would have master some of the coding language and may be want to particularly check where you stand with the skills you have developed among the others who are deploying their skills in this small world. Because the level of competition is very high, since each one of us is better than other and becoming more and more better. Hence to make a count on yourself Competitive Coding provides the best outcome which will have you to access and know better of your coding skills. But before that let’s know what actually Competitive Coding Means.

What is Competitive Coding 👨‍💻

As Wikipedia says, competitive programming is a mind sport usually held over the Internet or a local network, involving participants trying to program according to provided specifications.

Basically, it is a type of contest where a number of programmers attempt to solve programming questions in a limited amount of time with under some preconditions set by the organizer. You can write your solution in any programming language that you’re comfortable with. Solutions should pass all of the test cases (given and hidden) in order to be accepted under certain time and space limits.

Time and Space Complexity plays a very major role in competitive coding. You might pass all the public and hidden test cases and your code would have satisfied all the given conditions, but if the written code is not efficient in the time and memory aspect then you can’t win any competitive coding contest. Best Code should take the least possible time and memory (i.e., space) to compile and run to provide the best outputs.

Big tech companies, like Facebook, Google, Amazon, Microsoft etc hire through competitive programming competitions. As an added bonus, various online competitions offer some amazing prizes for the winners.

Major Benefits of Competitive Coding 👨‍💻

1. Helps you to do a coding task in a stipulated time – Need to Complete a given task with in the given time range, hence it indirectly increases you thinking and working capabilities.
2. Cracking the Job Interviews – It definitely helps one to prepare for technical and coding interviews as the questions and the contests held make you more ready to crack any interview.
3. Strengthen your programming and software knowledge – As you practice more and more on certain portion it indirectly makes you master of that thing.
4. Helps you to land a job in Dream Companies – There are many examples of this where a lot of aspirants got their dream job after practicing, coding and competing in such platforms.
5. Increases your Problem-solving skills – As you solve an enormous number of problems it makes problem solving as your habit and you are able to think and come to the logic quite fast, that is why it increases your problem-solving skills.
6. Helps you better to work in a team – Since most of the coding contests take place as a group of some coders, hence it taught you how to work better with a team and lead to success.
7. Better self-assessment and correct the mistakes – All of the platforms provide you to keep track of your activities and the mistakes that you have done, hence it helps to assess yourself and not to repeat a mistake again.
8. Makes you faster and more focused – With continuous practice and time on these platforms you become faster and more focused to solve the particular problems.

Hence, what we can say that the benefits from Competitive coding is endless as it helps us to make better day by day, here only some of the main benefits have been listed which are mainly to motivates you and dive directly to the choice of your platform to prepare and compete with all the coders and programmers out there in this world.

Prerequisite for Competitive Coding 👨‍💻

There are some basic and important conditions that have to meet before you start for competitive coding, this is because if you start without these condition then at each point you will stuck with some or the other problem and at last, finally you will give up with the competitive coding. So, the prerequisite are –

• Pick a suitable language to code, in my opinion C++ is best for competitive coding.
• Choose a powerful code editor to run and compile your code, VS Code is best suitable to use in my opinion.
• Select a few platforms to practice, some of the best platforms are listed below.
• Make clear with the Data-Structures and Algorithms, good hands on these are very much required in competitive coding.
• Solve different kinds of problems to build a great confidence on your coding skills.
• Most important is to have continuous involvement in practicing.

Note : Remember one cannot master a skill in a night, it takes continuous passion and determination to master such things.

Now let’s list down the competitive coding platforms where you can show case your skills and knowledge among all others.

Note : Most of the below listed competitive platforms are not suitable for beginners. But you can at least try to explore these and gain some basic knowledge.

List of Top 10 Competitive Coding Platforms 👨‍💻
