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

I feel like I am GENIUS.

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

Firstly depressed...but finally enjoyed this question

My code is working fine for any input I enter, but spoj is showing WA. Is my algo wrong?(id=16204230)
2016-01-28 20:55:23
nvm, solved my problem. i just had to change my loop-iterators to int64_t's instead of normal int's haha ;D

I whish spoj would show which test-cases i got wrong answer on, would make bug-finding much easier. i mean if i run the computer manually, all of the test-cases i can think off give me the correct answer.....

for those who r getting wrong answer and are sure about there program just put a next line or endline after each cout and cin statements.Maybe this works it WORKED for me
