PALIN - The Next Palindrome
A positive integer is called a palindrome if its representation in the decimal system is the same when read from left to right and from right to left. For a given positive integer K of not more than 1000000 digits, write the value of the smallest palindrome larger than K to output. Numbers are always displayed without leading zeros.
Input
The first line contains integer t, the number of test cases. Integers K are given in the next t lines.
Output
For each K, output the smallest palindrome larger than K.
Example
Input: 2 808 2133 Output: 818 2222
Warning: large Input/Output data, be careful with certain languages

Nice problem - a hint is to think about the cases for the odd number of digits and even number of digits separately |

I can't figure out which number is breaking my code :( I've made a test case of thousands of random numbers and they all passed. I'm out of ideas :( |

Hi! I want to know if anybody can send to me a list with all cases of input ? My problem is that I'm not sure if input can be for example: 005 and if it can, which is the next palindrome ? 6 or 101 ? Thank you |

This is one question that teaches you case handling.
