What is competitive coding?

The term 'competitive coding' refers to a format in which teams of programmers compete against one another to solve real-world programming challenges within a predetermined time frame and other constraints. Programmers who compete in these coding tournaments are referred to as 'sports' programmers.

Many do it as a means of earning a living, while others do it simply to improve their coding abilities. Participating in a coding competition not only enables you to evaluate your skills as well as your level of expertise but also provides you with the opportunity to evaluate your performance in comparison to that of other programmers from all over the world. Apart from that, individuals participating as programmers are eligible for a wide range of opportunities, including internships, jobs, awards, and scholarships. 

Do you know? One of the oldest contests, International Collegiate Programming Contest (ICPC) originated in the 1970s and currently has over 88 countries participating in it. 

It is important to bear in mind that aggressive programming is not a skill that can be picked up in a matter of days before beginning to work with it. To start, there is going to be a necessity for some amount of time in addition to a substantial amount of practice.

Reasons to take part in competitive coding events

Coding is considered to be a challenging profession. And, once you begin working in this field, you might face new issues that no one else tackled before and you might be required to address them. At a certain point in time, it will be essential for you to start making use of your academic ability for problem-solving talents as well as logical arguments to come up with an optimal solution in the shortest time limit or via the shortest path available.

If you want to work for major companies such as Microsoft or Amazon, which hire employees via competitive programming, then you have to get your hands dirty in the domain. You need to follow some steps and strategies to prepare you for competitive programming. It doesn't matter how long you have been programming or how much code you have produced in the past; you need to perform absolutely the best.

Here are some reasons for why one must competitive coding events: 

1. Face new challenges: Competitive coders address a wide variety of problems spanning many domains, including number theory, combinatorics, data structures, graph theory, sets, pure calculus, mathematics, and numerous others. As a result, they help in addressing difficulties that arise in everyday life, such as determining the quickest route from the origin to the destination, calculating interests, or determining the fewest number of moves possible. Through consistent practice, one can increase his/her capacity for both analytical and creative thinking.

2. Prepare yourself for technical interviews: The conventional coding interview is somewhat similar to a programming competition in many aspects. Each of these calls for the resolution of precisely outlined programming problems and tends to emphasize widely used methods rather than industry-specific technologies, and offers bonuses for finding solutions quickly.

3. Showcase your technical skills: The majority of developers do not have any sort of public record apart from their CV, which frequently contains statements that are challenging to confirm because they entail non-public work. Thus a competitive programming score or a history of committing code to projects hosted on GitHub is really useful. Both of these are ways to demonstrate that you can code.

If a hiring manager notices a link on your curriculum vitae that displays your competitive programming contest performance, then he/she is more likely to call you for an interview. 

4. For enjoyment: Entering programming competitions to improve one's programming skills provides motivation, similar to that provided by joining an amateur sports league to increase one's level of physical activity. It is a good strategy to keep yourself motivated and upskilled. So for people who love to compete, coding competitions are indispensable events. 

5. Level up your coding skills: For a software engineer, writing a brief program in 30 minutes to solve a challenge is different from writing a comprehensive application. Thus, coding competitions help them to think outside the box and come out with the most creative solution to a problem. 

Competitive programming helps you become accustomed to thinking more rapidly and effectively. Because of this, you can arrive at the best decision in the least amount of time. As you become better at what you do, you will be able to transition from one job to the next much more easily.

What are the requirements to take part in competitive coding events?

Before we get into the tips for winning the competitive coding, we'd want to go through some of the criteria for competitive programming. When it comes to competitions, having the correct mindset may make a huge impact. Be sure to keep in mind that having all of the important details in front of you at the beginning gives you the ability to build a strong foundation.

Pick your programming language:  Although you can compete in any language of choice, C/C++, Java, and Python are the most commonly used languages. Hence, proficiency in any of the languages is essential for participating in coding events. 

Consider a faster programming language: The reason for this is the amount of time it takes for a program to be executed. So, if you select a programming language that has a relatively short amount of time needed to complete a program, then you will have a significant advantage over your competitors.

C/C++ and Java are comparatively speedier programming languages, especially when compared to other languages such as Python. 

Gain an understanding of the fundamental knowledge of algorithms and data structures: When it comes to finding the best answer to almost any coding issue, you will almost always need to make use of a particular data structure or technique. Hence, you must have a fundamental understanding of data structures as well as algorithmic procedures. Both data structures and effective algorithms contribute to the overall effectiveness of a program. Also, if you have a good level of knowledge in DSA data structures, then you will be able to select the best data structure for every problem as well as implement it using the logic which is the most optimal for that structure.

Building algorithms: The development of efficient algorithms that can tackle outlined computational challenges is at the core of the sport of competitive programming. The development of a basic algorithm calls for proficiency in both problem-solving and mathematical concepts. Also, competitive programming places a significant emphasis on mathematical skills. 

Learn space and time complexity: In the majority of situations, more than one solution to a problem already exists. Because of this, it is necessary to devise the most effective solution (also known as an optimal solution) which is determined by the amount of time and space that advanced algorithms require to resolve a problem. For this reason, it is of the utmost importance to acquire knowledge of these two principles before attempting to compose the best possible answer to the problem.

Try hard-level coding problems: You have learned a programming language. You have mastered time and space complexity. And, you've also covered the principles of DSA. Now, you should take part in coding competitions offered on a variety of different competitive programming platforms. It might be a good idea for you to practice basic programming challenges on your own as well before engaging in competitive programming and then you could participate in the coding contest itself.
