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

	Dmitri: 2014-05-13 15:09:33 Was worried if my program would take 1 000 000 chars string with Console.ReadLine() in C#. But got solution accepted at the first attempt :)
	The Mama of Coding: 2014-04-24 20:24:06 awesome problem!!! but not for beginners... took me 6 hours to fully understand it. thumbs up
	ANKIT KUMAR CODOPEDIAC: 2014-02-12 06:51:43 can u plz tell me at which test case this is giving wrong ans? [code removed] "1. Don't post any source code here." Last edit: 2014-02-12 08:04:04
	cegprakash: 2014-01-15 18:57:58 The problem's worth will increase after rejudge!
	Mitch Schwartz: 2014-01-15 16:16:38 @Łukasz Kuszner: Thanks! Moved back to classical. Will there be a rejudge? I can understand if it's too much work for the servers to rejudge over 70k submissions, considering also that the problem is currently worth < 0.01 points.
	kuszi: 2014-01-15 15:23:59 Tests are a little stronger, what about moving it back to classical?
	Mitch Schwartz: 2014-01-15 15:17:31 Moved to tutorial.
	Subhasish Saha: 2014-01-15 15:17:31 Many people have commented but still test cases have not been corrected!!! For input 523526236747348343262362486125986592, accepted solution gave 523526236747348344443843747632625325. Whereas correct output is 523526236747348343343843747632625325. Is there any admin/moderator?
