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

Note for WA:
The last output line can't include the newline, or it'll cause WA...

>>>given positive integer K of not more than 1000000 digits<<<

Err..Does that line mean 7 real digits or do we really mean a million figures from 0 to 9 in this number??

Reply (numerix): As it says: 1 million DIGITS!

Note: There will be NO newline char at the end of last test case.

few test cases:
5 -> 6
9 -> 11
119 -> 121
192 -> 202
5403123 -> 5404045
12 -> 22
200 -> 202
0 -> 1
123456789 -> 123464321
987654321 -> 987656789
322222222 -> 322222223

what is the solution to single digit inputs
2015-01-30 15:06:56 vasu
Can this program have an input of the type 00002?
And in case it does, then according to the description, the solution would be 3. Is that correct?

Keep the following test cases in mind:
9999 -> 10001
99999 -> 100001
5 - > 11
10 -> 11
1299976 -> 1300031

why is the next palindrome for 5 11 ?
should'nt it be 6 ?
it satisfies the definition of palindrome given in the question
