Usually, by reversing any number and adding it to the original one it is possible to get a palindromic number after a few steps.
110+011=121, which is a palindromic number.It reads the same forwards or backwards.
This is a palindrome. the first number took just 2 steps and the second, 5 steps. but 196 is an exception as John Walker discovered on May 2, 1990.In spite of employing a computer programme to carry out this process of reversal and addition he had to abandon the effort after 2,415,836 steps that yielded a number with one million digits.Still there was no palindrome for 196
