Problem type

Reyno's family has an unusual tradition: upon buying your bus ticket, you check if it's lucky (and if it is, you eat it, but that's beside the point). Each ticket has a serial number containing an even number of digits, and a ticket is considered lucky if the sum of the digits in the first half of the number equals the sum of digits of the second half. For example, 113311 and 113005 are both lucky, but 113331 is not; the next ticket after 113331 that is lucky is 113401. Given the serial number of a ticket, find the serial number of the next lucky ticket.

Input Specification

The first line on input contains T (1 \le T \le 100), the number of test cases. T test cases follow. Each test case contains an integer N (1 \le N \le 10^{100}), the serial number of a ticket. N will have an even number of digits and may be given with leading zeroes.

Output Specification

For each test case, your program should output one integer, the next lucky ticket.
