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

isnt 808 a palindrome? In the test case, it isnt. but on the net it clearly mentions its a palindrome. What should i do?

m new on spoj..can anyone tell me ..how I can check that on which test case my code is not accepted |

Attention should be given that there could 1000000 digits in a number. |

Same problem here..I get the correct answer on my code, still I get the wrong answer here, If only we could see what test case the code failed at, it would be great. |

@quock The constraint is given on the number of digits |

I want to ask that if we have to find just preceding palindrome of the number then what should be the approach |
