Hi, beginner here.

//wins - horizontal

fun horizontalWin(letter: String, listIn: listOf<String>() ): boolean {

var counter = 0

for (element in listIn ) {

if (element == letter) {

counter++

}

}

if (counter == 3) return true

}

fun main(args: Array<String>) {

var row1 = listOf("X","O","_")

var checkForWin = horizontalWin("X", row1)

}

It s a bit rough and I am not sure if it makes sense, but I want to pass a list (or array) in and test it. Thank you.

next time please use triple backticks ` ``` ` to mark the beginning and end of a code block

also, is there a question? 🤔

Ah sorry, totally missed that from my draft! apologies for the formatting too, anyway, I want to pass a list as a parameter but, I am getting 'unresolved reference' for the list parameter in the function, is it possible to pass a list/array as a parameter to a function? If so, how? thank you.

ohhh, I see, just reread your message

Ah, thank you, I will give that a go. Apologies for the confusion again.

@ImranH also, consider the following equivalent but way more consise approach

fun horizontalWin(letter: String, listIn: List<String>): Boolean {
  val matches = listIn.filter { it == letter } 
  return matches.size >= 3
}

, or taken a step further

fun horizontalWin(letter: String, listIn: List<String>) = listIn.filter { it == letter }.size >= 3

I mean, I figure that’d be tangential to the goal of learning Kotlin basics

Thanks guys, I will have a play with those too. Appreciate it.
