Hi codeforces,

I am planning to make some introductory sessions and workshops to my college students.

In my university, it is not common to students to participate in problem-solving contests. So, I want some suggestions on how to impress my colleagues and make them like CP. Specially I want some easy-to-explain impressive problems. Some motivating reasons and words will be good as well.

Also, if someone has introduced CP to his people before, and he can share his experience that will be great!

Thank you
