plz… look at the question wa in next palindrome on this page @shashank13_
it gives wa on spoj & rte on codechef while i am unable to find what’s going wrong…
try out some corner test cases, test your code on against some random numbers and compare your code’s output with AC’ed code output, this way you’ll find the bug… !!
Happy debugging…
