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

clue: 1.) store and manipulate the input as string. 2.) brute-forcing == dumb |

NZEC = Non Zero Error Code, in this case most likely your program can't handle large input numbers (up to one million digits). |

hello guys what does NZEC means ?? My code is working in my machine and I try the test cases that I've read in the comments and the answers are correct. Thank you

nvm, solved my problem. i just had to change my loop-iterators to int64_t's instead of normal int's haha ;D |
