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

Single digit number is not a palindrom. It means if i enter 6 it must give 11 as output.is that right?? Or it should be 7 Last edit: 2015-04-23 19:08:07 |

One small suggestion for all people who are facing "wrong answer".. Single digit number is not palindrome. Do make sure your code handles it. |
