# Python Program

1. 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 109, 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. Followed by t lines containing integers K.

### Output

For each K, output the smallest palindrome larger than K in a new line.
