We create a string array `words` with unsorted elements.
We use the `sorted()` function to sort the array in ascending dictionary order.
We print the sorted array.

fun main() {
    val words = arrayOf("banana", "apple", "orange", "grape")
    val sortedWords = words.sorted()
    println("Sorted Array Ascending: ${sortedWords.joinToString()}")
}
