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

"For a given positive integer K of not more than 1000000 digits", really 1000000 digits or it talks about the input being less than it?

It works fine with python3, BUT do not convert ever from string to int (do not use int() on python) since it is a HUGE slow down of the running time, giving even a TLE error.

Does this work in python?

I think there might be something wrong with this problem / its judge.
