昨天一MM(老同桌)问了我一简单的算法设计题。题目就这个题目,算是很简单了,不过越是简单的事情越考验一个人的东西。
“To iterate is human, to recurse divine”——L. Peter Deutsch ( “人理解迭代,神理解递归。”)
问题不难所以就很快搞定了,让我再次回头看这个问题的原因是,这么简单的问题竟然综合了 iterate和recurse的方法。废话不说,贴代码如下:
运行结果:
代码没什么好说的,很简单。O(∩_∩)O~

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
