The Palindromic Number Calculator

Almost all numbers can be made into a Palindromic number by carrying out the following algorithm:

- Take the number, reverse it and subtract the smaller from the larger. (e.g. Using
1234:4321 - 1234 =3087)- Now repeat the same step with the new number.

(so here we would do 7803 -3087=4716

and then 6174 -4716- =1458

and so on ...Eventually, usually after a few steps, the result will be a palindromic number. Occasionally, we end up with an oscillating pattern.

The number of lines which will be displayed is limited at the moment to 100 lines.
