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

Warning: large Input/Output data, be careful with certain languages

	kamlesh_2209: 2017-09-01 06:58:25 thanks @milos94 ... your comment about printing answer with just a space and not endl helped me....
	jaykay12: 2017-08-30 22:25:48 AC in 3rd Go. :) Nice Problem. Be Careful with Number 9. :p Actually a String problem not an integer.
	prasanth292130: 2017-08-20 20:16:01 do we need to test for the negitive numbers???
	aryandosaj: 2017-08-19 16:07:33 i m giving output in prescribed format and also getting the correct answer but unable to submit.is there any extreme case to be checked.
	Sebastian Ceronik: 2017-08-16 09:50:18 Anyone else expiriencing problem with WA ? I mean I pass tests according to spojtoolkit. but get wrong answer :/ toolkit say that 001 supposed to be 010... what is up with this leading zeros that supposed to be ommited then ? tried both cases while submiting solution but no success in that . am I missing something ? some more test cases could be usefull maby ..
	kotal_kahn: 2017-07-15 18:35:51 hey i am using string to store large numbers then incrementing by 1 and checking if the reverse of the string matches is it correct way?
	m_sundriyal: 2017-07-14 00:00:37 if(problem==TLE) http://www.geeksforgeeks.org/?p=23497 if(problem==WA) Read this carefully "For a given positive integer K of not more than 1000000 digits" means that the number can be of 1000000 digits which cannot be stored in any data type. Some Important Test Cases Input 0 1 001 9 999 Output 1 2 2 11 1001 Thank me later
	md_hasnain: 2017-07-11 11:52:42 My code is running without any tle in ideone with time limit as 5s but giving tle in spoj... Last edit: 2017-07-18 10:08:15
