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 problem requires you to take care of so many test cases. There is a possibility of error even when you check for tricky cases like 9,99,100,101 etc. Also do remember answer for single digit numbers will not be 11. (edit)-> single digit numbers except 9. Last edit: 2015-06-22 10:16:41 |
