So many people want to improve their programming and coding skills but not everyone finds the proper resources to learn and practice it.
Some people are already good in coding and may want a platform to show their skills. Here I am offering before you a solution for both those who want to improve their coding skills and those who want to show their talent in coding/programming. One of the best way to do it is by participating in coding challenges as they can help you to improve logical thinking and will also help you to become successful in job interviews. In this article I am telling you about some of the best coding challenge websites.
Solving coding challenges is one of the best way to improve your coding and programming skills. Solving different types of challenges and puzzles can really help you to become a better problem solver which is the prime requirement of becoming a coder. By solving these challenges you can also learn the details of a programming language, learn new algorithms and to prepare for job interviews. Now I will explain about some popular coding challenge websites alongwith a short introduction about each of them.
CodeChef is a non-profit India based competitive programming website which provides hundreds of challenges. It has an online editor where you can write code. You can see many programming challenges in it which are divided into various categories based upon your skill level. They have a large community of coders which contribute to the forums, create tutorials and also participate in the CodeChef’s coding competitions. This platform mainly focuses on Algorithms and problems are put in categories like Beginner, Easy and Medium levels.
HackerRank is the largest community to learn programming online and practice it on the site. It has over 1 million programmers as its members. They have code sprints happening every month where many coders participate to win prizes. This website has coding challenges which are mainly divided into 3 difficult levels i.e. Easy, medium and hard. It also has challenges in Algorithm, Data Structure and Mathematics. It also has challenges for programming languages like Java, C++, Linux shell, Ruby, Python and functional programming. It has a special course called “30 days of code” for beginners in programming.
Leetcode has programming contents on Algorithms, Shell, Database, System design etc. There are new contests held every week in which winners are awarded special cash prizes and gift cards. It also has mock interviews and past sessions which help you to prepare for job interviews of top companies like Google, Facebook, Microsoft, Amazon, Yahoo, Uber, LinkedIn, Apple and many other companies.
Coderbyte provides more than 200 coding challenges which you can solve in an online editor using different programming languages. It also provides solutions for some of the most difficult challenges along with more than 8,00,000 user solutions. Coderbyte has been recommended by the top coding bootcamps because of it having a collection of interview preparation challenges. This website also provide courses in Web development, Algorithm and Data Structures and preparatory courses for coding bootcamps.
TopCoder is one of the best website for competitive programming online. It has many algorithmic challenges from the past which you can complete on your own directly online using their code editor. They offer popular single round matches per month at some specific time where you can compete against others in solving challenges. They also offer sponsored competitions where you can win prizes for writing and giving the best solution to the problem or challenge.
Project Euler is a website having series of challenging mathematical and computer programming problems which require mathematics plus some more skills to solve. The challenges it offer involve writing a small program to find out the solution to clever mathematical formulas or equation by creative thinking and problem solving. This process help you to learn, grow and know more about the language you are using. They offer one extra challenge per week for the coders.
We have just discussed the most popular websites for 2018 which offer coding challenges. By registering and participating in these sites you can not only learn coding, problem solving, algorithm implementation but it will also prepare you for the technical interview and tests if you want to appear for any company. Slowly you will gain enough confidence to solve any kind of programming problem and write any kind of code yourself.
