This chapter is designed to give you a taste of the types of coding problems you may encounter during a technical interview. It's a curated collection of various difficulty levels, each one designed to test your understanding of programming concepts and your ability to turn those concepts into working code.

It's important to note that solutions are not provided for these problems. The goal is to challenge you to work through the problems on your own and to develop the discipline to spend a fair amount of time figuring out the best approach. This will help you grow as a problem solver and better prepare you for future interview scenarios.

However, we understand that it can be difficult to get started on a problem, especially if you're stuck. That's why we've included an extensive list of test cases to explain the problems. But the ultimate responsibility of choosing the right approach and solving the problem rests with you.

By working through these problems on your own, you'll build your confidence and grow as a programmer. So, go ahead and give it a shot!
