Can you solve these code puzzles?

Hi guys 🙂

A few days ago I started working on a new project. The concept is solving code related problems and puzzles. These range from easy to very hard, and should be doable by anyone even without a coding background. More info: https://medium.com/@ilyanevolin/code-puzzles-by-codr-9738580fcf5b

The medium/hard/extreme levels are currently under construction. I am adding new puzzles on a daily basis, so stay tuned 🙂
