Reverse number : n = 234 1) n%10 => returns 4 add to a variable rev 2) n=n/10 makes n = 23 => rev = 4, n = 23 Repeat these two steps in a loop until n>0 => rev = 43, n = 2 => rev = 432 , n = 0 finally, You get rev = 432. Just find how to add.. Finally if original n = 234 is not equal to rev( =432) so it's not polindrome... Think for number 121: Reversing it, you will get 121 same so it's a polindrome. Hope it helps..
