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

For anyone stuck getting wrong answer - try this input: 2 1234567887654322 12345678987654322 It should output: 1234567997654321 12345679097654321 |

Why is the implementation difficulty so high? I found it to be pretty easy in both concept and implementation in CPP14 |

If you're getting SIGABRT then it means that you're probably converting the given string to int so you must not do that. You must solve the problem in the string itself as the input is too large. Moreover, if you're getting the Wrong Answer then you should use the test cases provided by @shreyas_07 in this comment section. They're around 1-2 pages behind the current page. They would help you debug your program. |
