    {

        //call the method and display the output

System.out.println("The swapped digit is: " + swapDigitPairs(482596));

    }

    //definition of "swapDigitPairs" method

    public static int swapDigitPairs(int n)

    {

        //declare the variables with the values

        int result = 0;

        int power = 1;

        //check the condition

        while (n / 10 != 0)

        {

/*declare and calculate the values for the variables*/

            int right = n % 10;

            int left = n / 10 % 10;

            //calculate the "n" value
