1. stream indexes and find index for min value
2. stream indexes, then filter out minIndex, then transform stream of indexes into values. in the end collecto values into array

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

need to sum not cound, wasted 30 minutes debuging, better read comments

Hi, totaly agree with you.
I've just forked someones solution.
Thank you for merging!)

It's not a bug, it just performance test...
You went over primitive range.

For a new pple, exceptions should be created outside SoulutionTest.class like a regular multiple classes in one file.

Hi, I think casting n.toDouble() and then i.toInt() could be simplified.
Check examples:

12 % 1
res0: kotlin.Int = 0

12.123 % 1
res1: kotlin.Double = 0.12299999999999933

2.0 % 1
res2: kotlin.Double = 0.0

123 % 1.0
res3: kotlin.Double = 0.0
