Name a popular resource for practicing coding challenges online.

HackerRank is indeed a well-known platform that provides a range of coding challenges for learners and developers. It offers a variety of problems tailored to different skill levels, focusing on different programming concepts, algorithms, and data structures. With a strong emphasis on competitive programming, HackerRank allows users to practice coding in multiple languages, and it often has challenges that are similar to those found in technical interviews.

Additionally, it not only helps in practicing coding but also in improving problem-solving skills, which is crucial when preparing for interviews in the tech industry. The platform also includes features for tracking progress and exploring solutions provided by other users, further enhancing the learning experience.

Other resources like LeetCode and Codewars also provide valuable practice opportunities. While Codecademy is an excellent educational platform for learning programming concepts and languages, it does not offer the same level of competitive challenge or focus on technical interview preparation as HackerRank does. Each of these resources has its unique advantages, but HackerRank is particularly notable for its robust selection of coding challenges designed to build and assess coding skills relevant to job interviews.
