public class Main {
    public static void main(String[] args) {
        // Step 1: Define the array with duplicate elements
        int[] originalArray = {1, 2, 3, 2, 1, 4, 5, 4, 6};
        System.out.println("Original Array: " + Arrays.toString(originalArray));

        // Step 2: Convert the array to an IntStream, apply distinct(), and convert back to array
        int[] arrayWithoutDuplicates = Arrays.stream(originalArray)
                                           .distinct() // Filters out duplicate elements
                                           .toArray(); // Converts the stream back to an array

        // Step 3: Print the array after removing duplicates
        System.out.println("Array without Duplicates (Streams): " + Arrays.toString(arrayWithoutDuplicates));
