some intermediate conclusions. I don't believe you recall how many times you thought"That's all. I think it's right, but you ask me, I can't tell you what's going on.".Don't you think it's strange? If you cannot logically support your conclusion, how can you be sure that it is correct? Just because your intuition strongly tells you that it is right? If there is another person next to him, he and you hold the opposite idea, and his intuition strongly tells him that he is right. What do you think

The nature of the heap no longer elaborated here, write this algorithm in order to better understand the STL heap algorithm, if you do not understand the STL algorithm can also refer to the algorithm here, because the pure C looks will save a lot of language details.
At the same time there is a STL in the corresponding algorithm test to compare the effect of both.

representative examples, in detail to analyze the MySQL encryption lock processing. Of course, from the simplest example. Often have a friend sent me a SQL, and then asked me, this SQL plus what lock? Just like the following two simple SQL, what locks do they add?
SQL1:select * from t1 where id = 10;
SQL2:delete from t1 where id = 10;
What is the answer to this question? One of the answers I can imagine is:
SQL1: no lock. Because MySQL is using multiple versions of co

Analysis and Elimination: Adjust the IRQ and I/O values in the NIC resources to avoid conflicts with other computer resources. In some cases, you also need to set a patch cord for the motherboard to adjust conflicts with other resources.
2. Fault Phenomenon: other clients in the LAN of the Internet cafe can see each other on the "Network neighbors", and only one computer can see either of them or another computer.
