PALIN - The Next Palindrome

#ad-hoc-1

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

	Minsuk Kim: 2014-11-27 09:28:45 Nice problem - a hint is to think about the cases for the odd number of digits and even number of digits separately
	Rafael Cunha de Almeida: 2014-11-19 04:10:12 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 :(
	NPR: 2014-11-18 12:23:02 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

	Manraj Singh: 2014-11-06 09:36:22 This is one question that teaches you case handling. SPOJ please start saving default complier.Costed me one Compilation error. :'( [reply by cyclops: Did you go to http://www.spoj.com/myaccount/edit/ and select a default programming language?] Last edit: 2014-11-06 12:05:31
