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

	Gaurav Agarwal: 2015-04-24 20:37:02 I cant figure out the test cases... can someone give me the outputs for the following input? 7 //no of test cases 5 8 9 20 98 998 6436
	shomit: 2015-04-23 18:57:41 Single digit number is not a palindrom. It means if i enter 6 it must give 11 as output.is that right?? Or it should be 7 Last edit: 2015-04-23 19:08:07
	Szymon: 2015-04-20 22:42:28 nice problem for tests coding 1 do brute force program 2 do your algorithm 3 compare results
	ashish: 2015-04-20 20:49:43 Hello admin/problem setter, can you please check why I am a getting wrong answer? Id: 14128402 Also can you please give at-least 1 testcase where I am getting a wrong answer?
	Anakar Parida: 2015-04-19 16:32:41 I am also fed up with wrong solution. Handled all cases from 1 to 999999999999999999. Dont know what else is needed
	Eknoor Jassal: 2015-04-19 15:49:39 I would restate what everyone is saying. I not " all about nines". Its about "all nines" ;)
	Anakar Parida: 2015-04-18 19:46:17 One small suggestion for all people who are facing "wrong answer".. Single digit number is not palindrome. Do make sure your code handles it.
	shomit: 2015-04-17 21:57:10 i have tried this code for every case yet it says wrong answer.Please list the difference test cases.....ughh i am fed up with this one
	saki: 2015-04-16 18:36:46 Guys i am new to SPOJ, not sure where to post my source code so that someone can check why it is showing wrong answer, I got exact o/p as mentioned in the question when done in Putty. Please help!
	akshay93: 2015-04-14 12:30:51 it works fine on code blocks but on the site its shows wrong answer. Guys please help.
