Write a method with the name reverse, that reverses a non negative integer passed to it. as an example, it should returns 456 when you pass 654 as the input. write a test method to test your reverse method (you can use it to test your method in main but comment out before you do the rest of the question). now, write another method with the name palindrome which takes a non negative integer and check if it is a palindrome. hint: you should use the reverse method you just created. make sure to give few test cases for palindrome method in the main method.
