between the first vertex and the starting position is 1000-977.57 = 22.43 kilometers.
So before the first transit, a total of 22.43*(2*7 + 1) = 336.50 liters of oil consumedAfter that, each transit consumes 500 liters of oilTherefore, the total fuel consumption is 500 + 336.50 = 3836.50 liters.
24 known (1) Each aircraft has only one fuel tank; (2) the aircraft can refuel each other (note that there is no fuel dispenser); (3) A box of oil allows an airplane to fly around the Earth in half a lap
php5.4 before the Json_encode when the Chinese will be Unicode encoding, Chinese will be encoded, become unreadable, similar to the "\u***" format, but also to a certain extent, increase the amount of data transferred. For example:

The problem is described as follows:
Each plane has only one fuel tank,Planes can refuel each other (note that there is no diesel generator)A box of oil allows an airplane to fly around the Earth for half a lap,Problem:How many planes should be dispatched to bring at least one plane around the Earth back to the airport when it was flying?(All planes take off from the same airport and must return to the
During the 11th, I went to Japan with my wife and adults.
The first step is to fly from Hong Kong to Haneda Airport. The Hong Kong Express is on a red-eye flight. The plane name is very interesting. It is called the shrimp dumplings. It took us three and a half hours to get from the Hong Kong International Airport to the Haneda Airport in Tokyo. The arrival time
In json_encode before php5.4, Chinese characters are unicode encoded and Chinese characters are encoded and become unreadable, similar to the format of "\ u, it also increases the amount of data transmitted to a certain extent.
For example:
Copy codeThe Code is as follows: $ Str = 'Chinese ';
Echo json_encode ($ str );
// "\ U4e2d \ u6587"
Php5.4
Echo json_encode ($ str, JSON_UNESCAPED_UNICODE );
// "Chinese"
Php5.4 make json better understand Chinese!Unicode transcoding is not performed before

In php5.4 before doing Json_encode, Chinese will be encoded in Unicode, Chinese will be encoded, become unreadable, similar to the "\u***" format, but also to some extent increase the amount of data transmitted.
For example:
Copy Code code as follows:
$str = ' Chinese ';
echo Json_encode ($STR);
"\u4e2d\u6587"
php5.4 start
Echo Json_encode ($str, Json_unescaped_unicode);

php5.4 lets JSON understand Chinese!
