If you've some experience as a developer, chances are you've wondered why you spent time learning about Big-O notation, complex algorithms, data structures, and more, especially if they don't seem directly applicable in your day-to-day coding.
But let's face it, it is a reality that these seemingly abstract concepts are part of a lot of code interviews, and while you may not use them explicitly in every project, they influence the way you approach problems, design solutions, and write code.
So, if you're preparing for technical interviews, or simply want to sharpen your programming prowess, these websites offer a wealth of resources to help you achieve your goals.
LeetCode is a popular platform among software engineers for practicing coding problems. With a vast array of algorithmic challenges ranging from easy to hard, LeetCode provides an excellent opportunity to hone your problem-solving skills. The platform also offers mock interviews and company-specific challenges to help you prepare for real-world coding assessments.
HackerRank is another fantastic resource for improving your coding skills. It features challenges across various domains, including algorithms, data structures, artificial intelligence, and more. HackerRank also offers interview preparation kits for popular tech companies, making it a valuable tool for aspiring software engineers.
Codewars takes a unique approach to coding practice by gamifying the learning process. On Codewars, you can solve coding challenges called "kata" to earn ranks and honor. The platform supports multiple programming languages, allowing you to practice in your language of choice while competing with other users in a fun and engaging way.
If you're looking for a more mathematically-oriented challenge, Project Euler is the perfect platform for you. Project Euler offers a collection of challenging mathematical and computer programming problems that require innovative thinking and problem-solving skills. It's a great way to stretch your brain and improve your mathematical and coding abilities.
Exercism provides practice problems in various programming languages, making it an ideal platform for learning and practicing coding in your preferred language. The platform offers mentorship and feedback from experienced developers, allowing you to improve your coding skills through constructive criticism and guidance.
These 5 websites offer valuable resources for improving your coding skills and mastering algorithms. The key is consistency: set a goal for the number of exercises to practice within a specific time frame, such as weekly, and stick to the plan. Create a routine that helps you develop this habit, for example, by solving one coding exercise before starting your day from Monday to Friday.
This approach will help you improve and maintain a good level of proficiency in solving these types of problems, increasing your chances of excelling in your next coding interview
