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

One thing that isn't really part of the problem that caused me some issues. The last (at least I assume it was the last) input doesn't have a newline character in it. Don't assume that all inputs do. |

@naman gupta (and others) Note that its integer k not more than 1000000 **DIGITS** so any c-derived 'int' type will not be big enough. Also implementing full arithmetic for bignums is overkill. This can be done by string manipulation. |

what is expected in case where the integer has more than 1000000 digits a test case: 3 808 integer more than 1000000 digits 2133 what should be the output??? [reply by cyclops: That is not valid input. We are given that K is not more than 1000000 digits.] Last edit: 2014-12-21 15:28:29 |

@Kushagra Bhatnagar: Why do you post your comment here, though it was a problem with your submissions for FIBOSUM? Explanation: You used Python 3.4 as language, but FIBOSUM is still on Pyramid cluster where Python 3.4 and PyPy are not available. Use Python 3.2 instead. |
