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 don't remember. Probably ignoreCase = true;

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

I mean that wasn't in the specification so not really necessary

Lack of reading comprehension in my case

no, if int can be in different position than 0

yes starting value of range() is 0 so defining it as 0 makes no difference.

LMAO!!!

Actually is multiplied by 0.5 liters of water.
Now you can easily change the hard-coded 0.5 to the new amount of water in the variable and the code will be the same.
Using divide by 2 just change the amount of water to 750ml and all code needs to be refactored.
