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

Note for WA: The last output line can't include the newline, or it'll cause WA... [reply by cyclops: No, you are wrong.] Last edit: 2015-02-07 05:03:35 |

>>>given positive integer K of not more than 1000000 digits<<< Err..Does that line mean 7 real digits or do we really mean a million figures from 0 to 9 in this number?? Reply (numerix): As it says: 1 million DIGITS! Last edit: 2015-01-31 20:32:37 |

Note: There will be NO newline char at the end of last test case. few test cases: 5 -> 6 9 -> 11 119 -> 121 192 -> 202 5403123 -> 5404045 12 -> 22 200 -> 202 0 -> 1 123456789 -> 123464321 987654321 -> 987656789 322222222 -> 322222223 |

Can this program have an input of the type 00002? And in case it does, then according to the description, the solution would be 3. Is that correct? |

2015-01-14 14:05:49 Anirudha Bose Keep the following test cases in mind: 9999 -> 10001 99999 -> 100001 5 - > 11 10 -> 11 1299976 -> 1300031 why is the next palindrome for 5 11 ? should'nt it be 6 ? it satisfies the definition of palindrome given in the question |
