Once to a company interview, interview asked the Java design pattern in a single case mode, let me write out with a pen, perhaps their own technology has not formed a system, the idea is not very clear, the results in a piece of paper written on the mess, the smear is not, unsightly. Often think of the scene at that time, it is really difficult to forget, but this experience is also good for me, let me have more understanding of the

Known: the code is as follows, and there is no suspense to injection. $ SortColumn = mysqli_real_escape_string ($ _ GET ['sort _ column ']);$ Query = "SELECT * from cr0_3 WHERE active = true order by $ sortColumn DESC ";?> Reasoning: 1. The number of cr0_3 fields can be determined through testing. If you don't know how to do it, don't read it down. 2. sort_column allows you to perform boolean judgment. It can be inferred that: (Case when (select ascii (SUBSTRING (password, 1, 1) FROM users where

I can see this question. A lot of people may need to hit the stone brother's board. What is the value of 7 + 5? How do you teach this? But in single-chip microcomputer, numbers are used Binary representation: This is just a bit of a logging/ Even though we have not learned a command for teaching materials. However, I mean to do a few experiments first to increase your interest in single chip microcomputer.
