Great solution!
In my approach, I had to convert n to a list first and then loop it backwards, but your solution is awesome!
It just shows how bad I am at math hahaha

Bro I was thinking the same, but forgot some little things hahahaha

this is better then mine, cuz I use if-else instead of this beautiful technique.

my top of mind solution was with the switch case one, but forgot some details so I use if-else to make it faster.
