import kotlin.test.*

fun main() { 
   //sampleStart 
               val list = listOf<String>()
            println("list.isEmpty() is ${list.isEmpty()}") // true

            // another way to create an empty list,
            // type parameter is inferred from the expected type
            val other: List<Int> = emptyList()

            // "Empty lists are equal"
println("list == other is ${list == other}") // true
            println(list) // []
            // list[0] // will fail 
   //sampleEnd
