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

what does it mean from "not more than 1000000 digits"? Do you mean no. of digits of the number is not more than 10^6 or the number is not greater than 10^6??

Is there something wrong is using Python 3.4. I am absolutely sure that I have an efficient solution(not loops etc) but I am always getting time limit exceeded. Any help is greatly appreciated. |

If I am getting 'Time Limit Exceeded' error does that mean my solution was correct but slow? Or it could also mean that its was slow, might be correct or incorrect? |
