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 you are getting too many WA ,try these test cases :9,11,99,100,9999 and check whether you are getting 11,22,101,101,10001 as answers...... Last edit: 2015-06-17 07:33:17 |

For all those who are getting SIGSEGV runtime error, do not use pointer char *s, although it runs on your system. Instead use the array with the size provided in the question is 1000000. This might help. :) |

Getting wrong answer.. even if the code is working fine on my system. Can anyone tell me the sample input to cross verify my solution ? |

Dealing with strings in Java gave TLE... Had to deal directly with array of short. |
