Idea: it is not difficult to see that the synthesis of each gem consumes a certain amount of magic, each gem has a certain benefit, so as long as we know the minimum cost of each gem synthesis, this problem can be converted into a full backpack with the initial magic value. The minimum cost of each gem can be calculated by running Dijkstra once and then the shortest path length is expressed by the synthetic cost.

Mr. Panda and crystal HDU-
Redis is a storage service that supports structures such as K-V and data can be implemented (memcache data is memory data and cannot be implemented)
Let's enter the redis world to find out.
Enter redis through the command line:
Use PS aux | grep redis to check whether the redis-server is enabled and the corresponding port number.
/usr/local/redis26/redis-server /usr/local/redis26/6007.conf
Connect redis command line to port

WHERE A. ' SKU ' = ' 6007-00d '
and a. ' Item_code ' =b. ' Item_code '
The above statement if ' 1_product ' does not have the corresponding ' item_code ' will result in the entire statement is empty, what is the method, do not because ' 1_product '. ' Item_code ' does not have the corresponding value, and causes the whole result to be empty, because I mainly want to check ' 1

Today, we continue to complete the video forwarding tool. We use udp to listen to the local port 8003 to receive the video forwarding requests sent by users.
After the program is completed, write a small tool to simulate the data request to test whether the program works normally.
At this time, something went wrong.
Test procedure:
(1) run the program in the Virtual Machine (Fecdora Core12)
(2) Use tools in the host to send simulated requests
(3) check whether the program works properly
However
server outputs "{[Error:read Econnreset] Code: ' Econnreset ', errno: ' Econnreset ', syscall: ' Read '} (if the server side listens to the error event, the server side throws an exception and exits). Why is that? I used the tcpdump tool to listen to the server port 6200 port, found the reason.When the CTRL + C key is pressed, the client on Linux sends a message with the fin tag to the server 16:53:59.948186 IP localhost.6201 > Localhost.lm-x: Flags [F], seq, ack 1 , win 257, options [Nop,nop,t
I. Batch build folder, bulk Read folder nameToday, the work encountered a problem: Boss gave us more than 200 companies ID code (such as 6007, 7920, etc.), need to search for the download news according to these ID numbers, so that the download to the news to the company ID generated under the specified folder! So the first problem is that more than 200 companies, it is impossible to download every time, you have to click: Create a new folder, and the

. Then run. Like windows and the compiler, a must first enter the memory before it can be run. For example, in TC2, the operation for running a is Ctrl + F9, and a enters the memory and is run at the same time. This process is very simple for common users. So, with the above concepts, let's further In-depth Memory, to see what will be found? We found that,Windows is in the area where the memory starts, followed by the compiler, followed by the program we wrote after the CompilerCodeAnd then the
