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

This is bullshit. Got time limit exceeded in Python 3, run time error in JAVA 6 and f**king compilation error in C++ 4.3.2 even though they all work fine in my system, and the interesting thing is that I joined SPOJ only today. |
