, because some of the upper-case letters are occupied by VIM.
The register command is double quotation marks.
For example, we want to copy the current row to register k. You should press "kyy. (You can also use V "ky. Why ?) Now the current row should already exist in register k until you copy something into Register k. Now you can use the "kp" command to paste the content in register k to the desired position.

To ensure the complete nature of the tree, you can first swap the root node with the rightmost node in the bottom layer, and then delete the node at the bottom right. This is possible to destroy the child node key is not less than the nature of the parent node. The method of maintenance is similar to insertion, starting at the root node, a

FTP is a File Transfer Protocol widely used on the Internet. Its disadvantage is that it transmits data in plaintext. It can easily obtain users and passwords by listening on nodes that pass through the data, which brings many risks to the installation, you can use SSL to encrypt the FTP connection. First, test the use of Tcpdump to listen to the ftp user name and password for plaintext transmission: tcpdump port 21-nA20: 03: 43.077038 IP 192.168.1.1.34453> 192.168.1.4.21: Flags [P.], seq, ack 1

Next, we use the coordinates of p and q points (x1, Y1), (X2, Y2) to obtain the coordinates of R = p + q (X4, Y4 ).Example 4.1: Obtain the elliptic curve equation y2 + a1xy + a3y = X3 + a2x2 + a4x + A6. The common points are P (x1, Y1), Q (X2, Y2) and the coordinates of R (X

Recently, the project needs to manage resources in multiple threads. Naturally, it comes to the idea of using smart pointers with reference counting technology to construct a garbage collection and recycling mechanism. The first consideration is the use of smartptr in Loki, which is already running in the project. Now we can see that Loki: smartptr is not as flexible as we think. The problem is that the constructor of smartptr (uses the original pointer to construct a smart pointer object ):Smar
