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

@shweta choudhary The problem is that the input number can have 1000000 digits, so int and long long won't work. Try to store it as a string and think of a different approach. |

Good problem. Just be very careful with what functions/operations you use in your language. Even in slower languages, this problem is easy to do with the high time limit. |

make sure that your program can accept numbers with at least 1000000 *DIGITS* Last edit: 2013-05-03 15:22:37 |
