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.


The first line contains integer t, the number of test cases. Integers K are given in the next t lines.


For each K, output the smallest palindrome larger than K.

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

Help? not able to figure out the problem.I'm not even using loops then also its giving tle..I'm coding in python..

My code is correct but it is showing TLE.Any help?I am using Java.

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??

i am getting time limit exceeded but i cant see a problem

Help? Getting SIGABRT. It seems like its passing all the test cases mentioned here in the comments though.
