Lucky Ticket

You are given a ticket represented as a string of digits. A ticket is considered lucky if the sum of its first half of digits equals the sum of its second half of digits. For example, if the ticket is '1230', the first half is '12' (with sum 1+2=3) and the second half is '30' (with sum 3+0=3), so the ticket is lucky.

Your task is to determine for each ticket whether it is lucky or not.

Note: Each ticket will have an even number of digits.
