<DIV style="FONT: 10pt arial"><B>Subject:</B> calculator sequence inspired by
my calendar</DIV>
<DIV><BR></DIV>Hello all,<BR><BR>In my today's page-a-day calendar, I've got
the following problem:<BR><BR>Zane is at least a year older than Mabel, and
both are at least 10 years old. If you write their ages on a calculator, one
age is the same as the other age turned upside down. If the difference between
their ages is as small as possible, how old is Zane?<BR><BR>So, I suggest the
sequence of numbers that can be represented as a differences between a
number on a calculator and the same number upside down. It is obvious that all
these numbers are divisible by 3. <BR><BR>I am not sure how to write a program
calculating them. Here is a sample:<BR>0 (1-1), 3 (9-6), 6 (65-59), 9 (21-12),
12 (98-86), 21 (89-68),<BR><BR>The relevant sequence: A045573 Still
numbers when turned upside down (only uses digits 0125689, with no final 0's).
