How can I effectively determine whether there are intersection of several sets of data ranges? php 5000 ~ 7000 2000 ~ 6000 8000 ~ 9000 4000 ~ 8500 5000 ~ 7000 In php, how can we more effectively judge whether there are duplicates of these groups of random data? Expected value: 2000 ~ 4000 4000 ~ 5000 5000 ~ 6000 6000 ~ 7000 7000 ~ 8500 8500 ~ 9000 Reply t

I saw an article saying that apache has a maximum concurrency of 3000 or 4000, and nginx is ten times higher than apache, but nginx is implemented based on caching, apache is actually 3000 or 4000. According to an article, the maximum number of concurrent connections allowed by apache is 3000 or 4000, and nginx is 10 times that of apache. However, nginx is implem

Use the table and materialized view logs created above to create three materialized views that are refreshed quickly.

On the Internet, I often ask what is the maximum length of Oracle varchar2? In fact, this name is not accurate. varchar2 is used in both oracle SQL and pl/SQL. oracle points out in the SQL reference manual and pl/SQL reference manual: the maximum length of oracle SQL varchar2 is 4000 bytes, while that of oracle plsql varchar2 is 32767 bytes. This is why a friend asked why 32767 characters (character/byte) are defined in pl/SQL, and the table fields ca

There areCode: VaR num = 2; function auto () {alert (Num);} setTimeout (Auto (), 4000 ); In this sectionProgram. That is to say, if you reference a function using the above method, the timer does not work. Similarly, the code above setinterval cannot work normally. The program can only pop up a warning box once and then report an error. Change the timer Setinterval ('Auto () ', 4000); setTimeout ('Auto

programming. Because we need to implement point-to-point communication, we have to combine the customer and server modes into one mode so that the server can be a customer, the customer can also act as a server so that both parties have the ability to call the other party and receive the call from the other party. This only requires adding a listening socket. Once the call connection is established successfully, a data stream is established between the two points. Even if both parties do not sp
