How to implement MAP in my code?

Question

I have a problem in my Kotlin programming code. The problem is as follows:

"Todo on this exercise should be done by utilizing MAP, a collection that can store data in a key-value format "

I'm confused as to how to implement it into my code. My code can be found here: https://code.sololearn.com/cfpYu5jaE11f/#kt

If there is an error in the code I write, you can change it.

Thank. Hope your day is fun!
