        int n = 10;
        int[] array = new int[n];
        for (int i = 0; i < n; i++) { array[i] = i + 1; }

        int delnum = (int) (Math.random() * n + 1);
        System.out.println("Удалённое число: " + delnum + "\nМассив: ");

        for (int i = 0; i < n; i++)
        {

            {
                System.out.println("[" + i + "] = " + array[i]);
