Remove array duplicates in Kotlin
Removing duplicates from arrays usually involves looping through an entire array and creating a new array without duplicates.

fun removeArrayDuplicates(duplicates: Array<String>): Array<String> {
return Arrays.asList(*duplicates).toSet().toTypedArray()
}
fun main(args: Array<String>) {
val duplicates = arrayOf("a", "b", "c", "a", "c")
println(Arrays.toString(removeArrayDuplicates(duplicates)))
// [a, b, c]
}
A Set is a collection that contains no duplicate events, so converting an array to a Set will get rid of all the duplicates.
