        int[] numbers = {5, 1, 9, 3, 7};
        System.out.println("Original array: " + Arrays.toString(numbers));

        // Step 2: Sort the array in ascending order
        Arrays.sort(numbers);
        System.out.println("Array sorted ascending: " + Arrays.toString(numbers));

        // Step 3: Manually reverse the sorted array to get descending order
        int n = numbers.length;
        for (int i = 0; i < n / 2; i++) {
            int temp = numbers[i];
            numbers[i] = numbers[n - 1 - i];
            numbers[n - 1 - i] = temp;

        // Step 4: Print the array after reversing
        System.out.println("Array sorted descending: " + Arrays.toString(numbers));
