fun <T> Array<out T>.distinct(): List<T>
fun ShortArray.distinct(): List<Short>
fun FloatArray.distinct(): List<Float>
fun DoubleArray.distinct(): List<Double>
fun BooleanArray.distinct(): List<Boolean>
Returns a list containing only distinct elements from the given array.
The elements in the resulting list are in the same order as they were in the source array.
