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

Before writing code, try to think of as many tricky test cases to cover all cases. then this problem became easy |

I will say, just be careful of edge cases and its simple, HINT :- use char array, it might be helpful(initially i tried with int, and then switched to char array :P) Question difficulty :- easy Implementation difficulty : - HARD |

solskgaer you can't take the same number as a palindrome like you are doing in case of all 9s |

Program works fine on all test cases but I am getting this unusual error "runtime error (SIGABRT)". What should I do?? |
