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

Why aren't single digit numbers considered palindromes? They should be. Mine kept failing until I forced it to output 11 on any single digit. From wikipedia (http://en.wikipedia.org/wiki/Palindromic_number): "All numbers in base 10 with one digit are palindromic". |

I wrote the program and it works fine and gives the results as expected. But still when I submit it here, it says wrong answer. I can think of the problem. How my program is going to be evaluated? I've assumed that input is entered and then enter key is pressed to get the result. How the inputs are going to be fed? More importantly, how should design my program to be properly fed testcases inputs in here? Please Help Last edit: 2015-03-07 21:59:02 |

Admin, I was getting TLE and then i read your comment that input does not end on new line. is that the case with individual input numbers as well ? i modified the program to include both new line as well as space to separate input numbers but still getting TLE |
