Feature Request : add learning resources

[abiyyu03]

Describe the solution you'd like
in this project, I haven't seen any resources about tools that make it easy for programmers to run their code in a browser. In addition, a website that provides programming practice questions is also worth adding to this project. For that, I ask to add some websites such as:

• LeetCode
• HackerRank
• Replit (in-browser IDE)

Additional context
Algorithms, data structure, in-browser IDE, learn competitive programming, learn basic programming
