+ * 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.
