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

I did a correct algorithm, but it is limited to the integer received (2.1b?) Even if I could put the 1000000 digits to an integer vector, how am I supposed to receive the number? Last edit: 2015-12-28 20:20:56 |

Go through ALL the comments to debug if you're getting a WA for no apparent reason. No shit. You'll find the reason. |

Getting NZEC despite my implementation working perfectly on my computer, even with a single 1 mill input, on python 2.7.1. Argh! |

Code is running perfectly on local machine with small trial input combinations! but getting 'NZEC runtime error' in Java language! what could be the problem??? |

All my outputs are correct but on submitting the code it's showing wrong answer and what does : " Numbers are always displayed without leading zeros. " mean? |

<Beginner feedback> <c++ 5> I took almost 1week for this problem.if you get TLE or Signal 11 error,there is a mistake in your implementation.try optimizing the code ,reduce the number of loops. if you get signal 11 error ,there is a problem in some initialisation. i used two dimensional array which caused TLE.i can say single dimensional array is better. reducce the loops for not letting it getting stuck in TLE.
