a 8-digits palindromic number is a number consisting of a 4-digits number written and then written backward, i.e. 1234 4321
so there are as many palindromic 8-digits numbers as 4-digits numbers so from 1000 to 9999,
so there are 8999 palindromic 8 digits number
(I assumed that 00011000 is not to be considered as a valid 8 digit number)
