Congratulations on completing the course on data structures!

You've done a great job, and now you deserve to receive your certificate. Data structures may seem challenging at first, but the more you practice, the easier it becomes to master them.

The last section might have seemed particularly difficult, but do we ever learn something without facing challenges? Difficulties toughen us up and add to our knowledge and experience. I've prepared a quiz for you that will help refresh your memory and test the knowledge you've gained during this course.

And here's a piece of advice for you: practice is the best friend of any programmer. The more you practice, the better you become. You already have enough knowledge to write small programs or perform complex calculations. In general, you are capable of creating a simple backend for an online store and much more.

Good luck, and thank you for staying with us!
