AddUser and useradd instructions are the same instruction (via symbolic link symbolic link).
Use permissions: System administrator.
AddUser is to increase the user. In contrast, there are also instructions to delete the user, Userdel. Syntax: Userdel [login ID]

Migration of login accounts and database users in SQL Server, SQL Server
1. Create a login name for SQL Server Authentication and map it to the database.
For example, if you create a user [kk] To map to the database [mytest], the database [mytest] will add a user [kk].
2. Delete the logon name [kk]. After deletion, the database [mytest] will have an isolated

In the tug-of-war competition, the number of people on both sides cannot exceed 1. Try to bring the strength of both sides closer.
Backpack ideas
In the initial equation, people's "physical strength" is taken as the benefit, and at the same time as the cost.
F (I, j, k): the former I used j physical strength, and the former I used k.
F (I, j, k) = max (F (I-1, j, k), F (I-1, j-a [I], k-1) + a [I])
In this way, we can get the maximum physical strength of half, but the complexity of the cycle its

Array traversal problem $ arrarray (10 gt; array (12 gt; 0), 15 gt; array (30 gt; array (35 gt; 0 ), 31 gt; array (40 gt; 0) how can we get the path from the top to each root node? For example, the final result is as follows: $ a [] array traversal
$arr=array('10'=>array('12'=>0),'15'=>array('30'=>array('35'=>0),'31'=>array('40'=>0)))
With the above array, how can we get the path from the top to each root node?
For example, the final result is as follows:
$a[]='10,12';$a[]='15,30,35';
