Here’s a puzzler for you. Guess before running.

“` fun main() {
val a = listOf(“000”, “001”).map {it.toCharArray()} val start = CharArray(3) { ‘0’ }

println(start) println(a[0]) println(start in a) println(a[0] == start) println(a::class.simpleName) println(a[0]::class.simpleName) println(start::class.simpleName) 

} “`

Just wasted an hour on it.
