Hey, you should learn the programming basics from a other tutorial website, Codingame is more like a playground where you can practice your new knowledge.
Once you got some basics
- What's a variable
- What's a if statement
- How to write/print data
Then you should be able to do the Onboarding and the Descent.
Don't worry, if you're stuck, use the Hint system, or ask for help on the chat/forum.
