Choosing a platform to host, document, and present your algorithm projects is the first step. Depending on your preferences and goals, there are many options available. GitHub is a great platform for version control and collaboration, allowing you to create repositories for your projects, write README files, add comments, and showcase your code. CodePen is ideal for front-end web development, enabling you to create, edit, and share HTML, CSS, and JavaScript code snippets with real-time results. Kaggle is an excellent platform for data science and machine learning, providing access to datasets, competitions, notebooks, and the ability to share insights and models. Finally, Medium is a great choice for blogging about your algorithm projects, as it allows you to explain your approach, share results, and embed code blocks or images.
