Description
Before bridges were common, ferries were used to transport cars into SS rivers. river ferries, unlike their larger cousins, run on a guide line and are powered by the river's current. cars drive onto the ferry from one end, the ferry crosses the river, and the cars exit from the other end of the ferry.

POJ 3282 Ferry Loading IV (simulation, queue)
A car crosses the river through a ferry. The ferry starts to enter the vehicle order on the left. The total length of the car to be transported on both sides of the river cannot exceed the length of the ferry itself. how many times can a ship cross the river at least run all vehicles?
Simply simulate the creation of two queues to install the left car and the right car to calculate the minimum transportation required on both sides.

If you want to buy a car, you need to know what the car is like. Go to the car house and make it easy to use. Look at the configuration of the car and search for what you don't know.
For a long time in automobile manufacturing, the basic principle is not changed. The fuel piston rotates and a shell is added.
1. First, I want to explain the purpose of buying a car by myself.
It is nothing more than walking, home, going out on weekends, and seeing the elderly.

1. Create a new database: sqlite3 filename
First set up a DB directory, and create a test.db database file in the DB directory, open the console window, the command is as follows:
Copy Code code as follows:
mkdir Db
CD Db
Sqlite3 test.db
2. Open a database that already exists: Sqlite3 file name already exists
Creating a new database is exactly the same as opening a database command that already exists, or if the file does not exist in the curr
(var i=0) used in the loop.Statement 1 is optional, that is to say, no statement 1 is used.You can initialize any (or more) of the values in statement 1:
for (var i=0,len=cars.length; i{document.write (Cars[i] + "}
You can also omit statement 1 (for example, when a value has been set before the loop starts):
var i=2,len=cars.length;for (; i{document.write (Cars[i] + "}

It is estimated that the market potential of semi-automatic driving and fully automatic driving vehicles will be considerable in the coming decades. In 2035 alone, for example, there will be about 8.6 million autonomous vehicles in China, of which about 3.4 million are fully autonomous and 5.2 million are semi-automatic.
"Sales of Chinese cars, buses, taxis and related transportation services are expected to exceed $1.5 trillion in annual revenue,"

First of all, let us assume that there is a world in which there is only one car that never lacks power. Cars are of the next generation, and there is no backward equipment such as the throttle steering wheel, there are only
