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

It is possible to use cin/cout and get AC |

The input can have leading zeros. Be careful of input like this 000001. Simply consider it as 1. Costed me 3 WA |

Very nice problem spent lot of time to solve. one thing is k=1000000 digits.. so you have to solve it using string |

rogu_auto you can use int to store K as it is only 10^6 wheras integer limit in c++ is ~10^9. |
