Answer:
The quicksort pivot is an arbitrary element within the collection that is being sorted. Using the pivot point, the collection of elements is partitioned into two smaller lists of elements. Using some logic, the smaller elements are placed left of the pivot point, and larger elements are placed to the right of the pivot point. Ideally, you would prefer you pivot point to be a median of your dataset to optimize the creation of the two sublists into a balanced state.
Cheers.
The pivot of a quicksort algorithm ought to always be the element in the middle. Some algorithms will choose the item in the center as the pivot, while others will choose the first or last element.
What is quicksort algorithm?Quicksort is a sorting method that operates in-place. It was created by British computer scientist Tony Hoare and is still a widely used sorting algorithm.
When properly implemented, it can be slightly faster than merge sort and two or three times faster than heapsort.
The quicksort pivot can be any element in the collection being sorted. The collection of elements is divided into two smaller lists of elements using the pivot point.
Smaller elements are placed to the left of the pivot point, while larger elements are placed to the right of the pivot point.
To optimize the creation of the two sub-lists into a balanced state, you would prefer your pivot point to be the median of your dataset.
Thus, this way quicksort works.

How are the waterfall and agile methods of software development similar?
Both methods allow project teams to complete small portions of the entire project in small sprints and work on different steps simultaneously.
Both methods focus on development rather than planning, in order for project teams to work more quickly.

In point 1, Both method, it divides the project into small parts, at it the working is easy, that's why it is correct. In point 4, Both method, it requires the documentation, that's why it tracks the project.

[tex]3x - 5 = 3x - 7[/tex]
Answer:
x = -1/2
Explanation:
Hey there!
To solve for x we need to simplify the following,
3x - 5 = 7x - 3
-3x to both sides
-5 = 4x - 3
+3 to both sides
-2 = 4x
Divide both sides by 4
-1/2 = x

As the security administrator for your organization, you must be aware of all types of attacks that can occur and plan for them. Which type of attack uses more than one computer to attack the victim?
Answer:
The answer is "DDoS "
Explanation:
The distributed denial of service attack (DDoS) occurs whenever a directed program's wireless data or assets, generally one or even more application servers, were also swamped by various machines. This attack is always the consequence of many affected systems, that fill up the target network with traffic.
This attack is aimed to avoid legal customers of one's website from accessing it. In being effective in a DDoS attack, further demands need to be sent to the hacker than even the victim's server could deal with. One other way to successfully attack is to send fake requests from the attacker.
