At the beginning of the selection sort, we scan the entire list, find its smallest element, and then swap with the first element, placing the smallest element in its final position in the ordered table. We then start by scanning the list from the second element, finding the smallest element in the last n-1 element, swapping the position with the second element, and placing the second smallest element in its final position. In general, when I scan the list for the first time (the value of I from

Almost all unix and linux servers run the ssh server, which allows administrators to securely remotely access the server. However, unfortunately, recent attacks against ssh services are very common. This article describes how to use the pam_abl plug-in of the ssh plug-in authorization module (pam) to protect the machines running the ssh service from brute force attacks.
You can download and compile the pam_
The OpenSSH bug exposes the system to brute force cracking attacks.
OpenSSH is widely used to remotely access computers and servers. Usually, OpenSSH allows three or six logon attempts before closing the connection. However, Kingsley, a security researcher, recently disclosed a bug that allows attackers to execute thousands of authentication requests within two minutes after the logon window is opened. T

Problem Description: Requires finding the closest two points in a set containing n points. The original thought is that we should compare Euclidean distances between two points, and in fact, we can compare their squares, so that we can avoid the approximate solution of the square root.
