is there a more functional way to write this code?

fun main(args : Array<String>) {
    val input = Scanner(System.`in`)
    while (true) {
    
      var currentMax =0;
      var iWithCurrentMax =0;
        for (i in 0 until 8) {
            val mountainH = input.nextInt()
            
            if(mountainH >currentMax){
               currentMax = mountainH;
               iWithCurrentMax = i;
            }
        }

        println(iWithCurrentMax) 
    }
}

Looks like a fold to me

[pakoito]

the while(true) may be a tailrecM

@tschuchort fold? Let me try that first. I am not sure about tailrecM? @pakoito not sure I have come across that before. Could you provide example?

[pakoito]

It’s on Arrow, it’s a function that takes a function (Continue) -> IO<Either<Stop, Continue>>, where Stop is the final state, and Continue is the intermediate one, and IO is what you use to wrap the nextInt() safely

[pakoito]

it isn’t easy to translate, with the limitation of 8 each time

[pakoito]

start with the fold first

[pakoito]

for just 8

Okay
