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

Do we need to consider -ve numbers as well? |

pay attention to "K of not more than 1000000 digits"! u can't use a numeric variable to save K, u need a string variable! |

The hapless solver of this solver of this problem might have quite reasonably assumed that the input would consist only of digits and newline characters. If you're going to allow stray whitespace at the beginning or end of input lines, that should be mentioned in the input specification.
