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

LOL! can the input number have leading zeroes??
I am having a hard time getting rid of them.... :/

For people getting WA try test cases like 0,99,199
The outputs should be 1,101,202 respectively

should we input the values given in the example or leave the input to the computer?

its giving wrong answer everytime i submit.its working fine and the output is correct in ideone

can someone give me some idea on how to store the strings in this problem for later access when all the input has been finished?
2019-10-10 08:19:56
giving runtime error all the time
beside it is fully working on ideone

i written my code without using nested loop ,then also it raising ' time exceeded limit'
just used this ( if str(m)==str(m)[::-1]: ) in python3,
does anyone facing same problem?

"For a given positive integer K of not more than 1000000 digits", really 1000000 digits or it talks about the input being less than it?
