The algorithm sounds pretty easy to understand. But did you know that from the Bootcamp data we got, less than 50% of the 200 coding Bootcamp students were able to pass the algorithm test. Many programmers plunge into the world of programming but do not yet have an understanding and fluency in algorithms. Apart from being an abstract algorithm concept, they also don't have much time to learn it. Don't worry, Codr is here for it! Equipped with easy-to-understand material, quizzes to test your understanding, and exercises with visual aids to make it easier for you to understand the concept of algorithms. In addition, Codr also carries a gamification method that will certainly not bore you. What are you waiting for?
