~~~~~~~~~~~~~~~~~~~~


<pre>
So, we have one vacant place and 4 occupied places.


If you mean circular permutations, then we may assume that the vacant place is in position "North",

or "12 o'clock". Then 4 other positions are occupied by 4 cars, and we should calculate

the number of placements of 4 objects in 4 positions. It is precisely the number of permutations 
of 4 objects, which is 4! = 24.    <U>ANSWER</U>.

Solved.
