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

Please provide a sample of a number with 53435 digits...i think my whole computer screen will fill away. Is the language given in prob statement is wrong?? 1000000 digits should be replaced with only 1000000. Isn't it?

My code exceeded the time limit. Does that imply there would be any redundancy in my code ? |

use string not integer, refer to geeks for geeks article for next palindrome, don't forget to include case 0000000 and 000000xxxx where xxx can be any number. goodluck :) |

Why is it showing compilation error? When I run the same code on my computer, it works perfectly. |

Theoden's test cases are recommended, plus "23726 -> 23732" (this case took me a lot of time to figure out) |
