You should keep your prints inside the function scope. Here's an example:

fun replace(s: String): String {
    println(s)
    return s
}

Hi everyone. I am trying to solve the challenge, Exclamation marks series #11:
(Find all vowels in a string and replace them with Exclamation marks)
I am using the Kotlin language.

I am not looking for a solution but instead looking for the reason for the error that follows when I submit a simple test.

Here is my code:

fun replace(s: String): String = s

println(s)

return s

I get 4 errors all to do with my println() statement.

src/main/kotlin/solution.kt:2:1: error: expecting a top level declaration
println(s)
^
I was just trying to see what was being passed in to s.

Can someone explain to me what I am missing??

Thanks
