Just wondering if you would help me in my assignment, I've started on them.
I've done most of it except the following three questions.
(1) Any flight can be brought to the front of the queue ready for deleting (landing)
For example if the flight is in the back, we can bring it in the front
(3) In the flight ID, there can only be one unique letter, for example A, a, B, b, we cannot have A, A, but we can have A, a
Please help me, if you find it a little hard, just do what you can, or which one you can.
