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

Tricky test cases are Input: 5 9 100 999 4998 421999767 Output: 6 11 101 1001 5005 422000224 Question is correct and you are getting wrong answer because you left some cases that can't seem easily.I am also blaming admin but when check all cases given in comment section i get all correct but on 21st page of comment section i got a test case which is responsible for my wrong submission.

	alexakel: 2017-03-06 10:07:56 Is there effective test cases? How can I check, whether my program works well on this site? It is awful service. CodingGame in such way is more better
	satyamr1: 2017-02-23 14:02:07 How to store such a large number with 1000000 digits?
