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

0 -> 1 1 -> 2 2 -> 3 ... 9 -> 11 99 -> 101 999 -> 1001 9898 -> 9999 |

There are no leading zeros. |

Try for these test cases 0012100-->12121 0003-->4 You need to get rid of the leading zeros |

I've got AC and I don't think that the implementation is difficult. Nice C++ code needs less than 80 lines of code. Last edit: 2020-05-10 18:29:45 |

do i just increment the input by one and check if its a palindrome or is there a better and a faster method? |

Its logic is easy but implementation is hard. It took me one complete day to make logic that covers all cases and then AC in 1 go. |

When they say, that elements are not more than 1000000 digits, they are not joking, my char array in C was one element to short Last edit: 2020-05-04 01:17:10 |
