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

@Kushagra Bhatnagar: Why do you post your comment here, though it was a problem with your submissions for FIBOSUM?
Explanation: You used Python 3.4 as language, but FIBOSUM is still on Pyramid cluster where Python 3.4 and PyPy are not available. Use Python 3.2 instead.

Hi guys, why does it say "compilation problem" while ideone runs it smooth? (C++).

@Jasdeep: check for 10. It should be 11.

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 :(
