i dont think it does =))) seems callisto really is

Meh. I'm always thinking outside the box.

That was my next question. Is there a way to find the answer to this question without consulting a mult. table? There must be, but it's beyond me.

Oh ok, so brute force it is!

I'm going to ponder this for a bit.

i think the answer is 108.am i wrong?
anonymous

It aint a palindrome.
anonymous
  • anonymous
yes you are 108 isn't palindrome
jagatuba
  • jagatuba
Palindromes read the same backward and forward

im confused with palindrome.

181 is a palindrome but not 108

Methinks C++ can solve this question, using recursion maybe o.O

thnx a lot 4 all

Probably @arcticf0x but unless you figure out how to do on paper you will still be using brute force. @Callisto There are no prime palindromes of 18 because all multiples of 18 are divisible by 2.

yup.. after trial and error, i discovered this truth and thought that i've mentioned something wrong :S

I believe this is true for any doubled prime.

We can consider about 100 so multiples of the inputted number and test the condition, stop when its met. Yes, its brute force only.

Ther is a very fast way to generate the "Next Palindrome" and it can be tweaked to work here :)
