PALIN - The Next Palindrome


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

This problem requires you to take care of so many test cases. There is a possibility of error even when you check for tricky cases like 9,99,100,101 etc. Also do remember answer for single digit numbers will not be 11.
(edit)-> single digit numbers except 9.

Surprised, got AC in first try, without even debugging anything. :O

If the input number is greater than 1000000,then what am i supposed to do ?? should i terminate the program ??

if you are getting too many WA ,try these test cases :9,11,99,100,9999 and check whether you are getting 11,22,101,101,10001 as answers......
