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

The hapless solver of this solver of this problem might have quite reasonably assumed that the input would consist only of digits and newline characters. If you're going to allow stray whitespace at the beginning or end of input lines, that should be mentioned in the input specification.

It is showing correct output for 99 and 999. But when I submit the solutuion it says wrong answer. Can someone post the good test cases? Thank You in advance.

@badman98 you want to avoid using int(hugenumber) and try the approach of int(hugenumber[1]), think about how addition works in principle, replacing some substring (of length much lower than the entire string which shortens the execution) with some other substring. I hope you'll figure this out :).

@wrzoboo what do u mean by writing own custom function to add 1 how else we can do it without converting string to integer

@vritta and @vivek_dwivedi  I tested whether there are any numbers with a leading zero, and there aren't any, not even zero itself.

Thanks Vivek, have been stuck on that problem for days. Now I know it's their fault.

very good problem ! total shit test cases even admin don't know that 0 is not a positive no.
