/*
 * The bashemin parking garage contains a single lane that holds up to 10 cars.
 * There is only a single entrance/exit all cars are blocking its path are moved out.
 * the custmer car is driven out,and the othere cars are restored in the same order that they were in
 * originally.wap that process a group of input lines .
 * Each input line contains 'A' for arrival or a 'D' for departure,and a license plate number.
 * cars are assumed to arrive and depart in the order specified by the input.
 * The program should print the message when car arrive or depart .
 * When car arrives ,the message should be specift whether or not there is room for the car in the garage .
 * If thee is no room ,the car leaves without entering the garage.
 * When a car departs ,the message should include the number of times that the car was moved out of the garage to allow others ars to depart.
