Well it is an infinit loop. The only thing that makes it NOT infinit is that return also acts as break.
Which makes it a potential bug.

It's the original function performed with a recursive implementation instead of loop. It keeps using itself with the n / 10 parameter until one of the first two conditions is met. Pretty neat.

My maths lecturer would be appauled by your comment @Encription0001 :D This code can be refactored to any value of water when you multiply. You should never use proper fractions, e.g. 1/2 (/2) 1/4 (/4) as cases such as .75 would mean 3/4 and you cant use the divide operator without multiplying the numerator thats > 1. e.g. ((1/4)*3) and using integer conversion will always round down a floating point number.

i just realized now that substring exists. smh

I don't remember. Probably ignoreCase = true;

https://devdocs.io/kotlin~1.8/api/latest/jvm/stdlib/kotlin.text/replace

fun String.replace(
    oldChar: Char, 
    newChar: Char, 
    ignoreCase: Boolean = false
): String
