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.


The first line contains integer t, the number of test cases. Integers K are given in the next t lines.


For each K, output the smallest palindrome larger than K.

My program solves all possible cases, but overlooked the case 11, 1111, 111111

Why I'm getting wrong answer even if my program is working correctly, even for input 9 ?
Can SPOJ provide me the test case for which I'm getting wrong answer?
