Coding Challenge websites you can use to develop your coding skills and the best way to improve your skill when learning to code is by solving coding challenges.
Solving different types of coding challenges and puzzles helps you to become a better problem solver, refines your thought process, learn the intricacies of programming language, prepare for job interviews, and more.
Below is the list of top coding challenge websites with short descriptions.
HackerRank provides challenges in various domains like Algorithm, Mathematics, Language-specific, SQL, and AI challenges. You can solve the challenges in various programming languages like Python, Java, Javascript, Ruby, etc. It gives every coder a rank based on the number and level of problems solved.
They provide leadership board and discussion for every challenge and most challenges comes with editorial that explains more about the challenge and how to approach it to come up with a solution.
It also provides the ability for users to submit applications and apply to jobs by solving company-sponsored coding challenges.
HackerEarth Practice offers programming tutorials (data structures, algorithms, math, Python, machine learning, etc.) and practice problems for developers to hone their skills and showcase their profile.HackerEarth Contests include hackathons, programming challenges, and coding competitions for developers and companies.
It helps organizations source, assess, interview, and hire top tech talent from anywhere for all developer roles. With the help of their products and online hackathons, HackerEarth provides remote hiring solutions for organizations worldwide.
The HackerEarth University Ambassador Program is a platform for students to run programming club in their university.
Codewars is a community for computer programming. On the platform, software developers trained on programming challenges known as kata.
These discrete programming exercises train a range of skills in a variety of programming languages, and are completed within an online integrated development environment.
On Codewars the community and challenge progression is gamified, with users earning ranks and honor for completing kata, contributing kata, and quality solutions.
CodeForce is also one of the best competitive programming platform and it offers short (2-hours) contests, called “Codeforces Round”, held about a week, educational contests (2-2.5 hours, with 24 hours hacking period), held 2-3 times per month.
Here you can challenge or hack other contestants solutions and solve problems from previous contests for training purposes.
LeetCode is a popular Online Judge that provides a list of 190+ challenges that can help you prepare for technical job interviews.
You can solve the challenges directly online in one of 9 programming languages. You are not able to view other users’ solutions, but you are provided statistics for your own solutions such as how fast your code ran when compared to other users’ code.
They also have a Mock Interview section that is specifically for job interview preparation, they host their own coding contests, and they have a section for articles to help you better understand certain problems.
