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

if(problem==TLE) http://www.geeksforgeeks.org/?p=23497 if(problem==WA) Read this carefully "For a given positive integer K of not more than 1000000 digits" means that the number can be of 1000000 digits which cannot be stored in any data type. Some Important Test Cases Input 0 1 001 9 999 Output 1 2 2 11 1001 Thank me later |
