Solve problem in this site, there have plenty of oi problems, it will do you stronger.

the first problem is from IOI 2018 I suppose that it would be hard for me, or am I missing something?

Firstly, I recommend don't solve interactive problems at the beginning. And don't try to solve problem with full solution, you need to get subtasks: For example: At the beginning write O(3*n) and get 25 points, then optimize that for O(2*n) and get 60 points. I also don't solve problems full, I prefer get subtasks first
