Write a function named square_list that takes as a parameter a list of numbers and replaces each value with the square of that value. It should not return anything - it should mutate the original list.

Answer:

Algorithm :

1.START

2. sum=0 ; n=1 ; length = 1

3. sum = sum + n

4. n = n + 2

5. length = length + 1

6. Repeat steps 3, 4 and 5 until n <= 99

7. mean = sum / length

8. print(mean)

Explanation:

Sum initializes the addition of the odd numbers

n starts from 1 and increments by 2, this means every n value is a odd number

The condition n <= 99 ensures the loop isn't above range isn't above 100 ;

The length variable, counts the number of odd values

Mean is obtained by dividing the SUM by the number of odd values.

The modern computer system has been evolutionary. Modern computers have allowed for us to complete hard tasks rather easily. With modern computers, we are able to calculate advanced equations with the click of a button. Trends in computing like RTX can rapidly improve performance, rendering, and tons of other graphical heavy actions. In September of 2018, we got the first RTX card, now in 2021, RTX has become exponentially better than what it was in 2018. With the modern computers comes quantum computers. Quantum computing is estimated to be 100 million times faster than any modern computer. IBM, the company to make the first computer stated that we are in the decade of quantum computing. And who knows? Maybe quantum computing will come sooner rather than later.

The current term of a Fibonacci series is derived by adding the two previous terms of its sequence; and the first two terms are 0 and 1.

The code segment (without comments) that completes the program is as follows:

int T1 = 0, T2 = 1, cT;

   if (n < 0){

       return -1;     }

   for (int i = 2; i <= n; i++) {

       cT = T1 + T2;

       T1 = T2;

       T2 = cT;     }

   return T2;

With comments (to explain each line)

/*This declares the first term (T1), the second term (T2) and the current term (CT).

T1 and T2 are also initialized to 0 and 1, respectively

*/

int T1 = 0, T2 = 1, cT;

//This returns -1, if n is negative

   if (n < 0){         return -1;    

}

//The following iterates through n

   for (int i = 2; i <= n; i++) {

//This calculates cT

       cT = T1 + T2;

//This passes T2 to T1

       T1 = T2;

//This passes cT to T2

       T2 = cT;

   }

//This returns the required term of the Fibonacci series

   return T2;

At the end of the program, the nth term of the series would be returned to the main method for output.

c. mentorship programs taking place via the internet

Explanation:

The World Wide Web (WWW) was created by Tim Berners-Lee in 1990, which eventually gave rise to the development of Web 2.0 in 1999.

Web 2.0 can be defined as a collection of internet software programs or applications which avails the end users the ability or opportunity to share files and resources, as well as enhance collaboration over the internet.

Basically, it's an evolution from a static worldwide web to a dynamic web that enhanced social media. Some of the examples of social media platforms (web 2.0) are You-Tube, Flickr, Go-ogle maps, Go-ogle docs, Face-book, Twit-ter, Insta-gram etc.

Some of the main characteristics of Web 2.0 are;

I. Social networking.

II. Blogging.

III. Interactive comments being available on many websites.

Also, most software applications developed for Web 2.0 avails its users the ability to synchronize with handheld or mobile devices such as smartphones.

However, mentorship programs taking place via the internet is not a characteristic of Web 2.0 but that of Web 3.0 (e-mentoring).

The option that is not a characteristic of Web 2.0 from the following is mentorship programs taking place via the internet.

Web 2.0 speaks volumes about the Internet applications of the twenty-first millennium that have revolutionized the digital era. It is the second level of internet development.

It distinguishes the shift from static web 1.0 pages to engaging user-generated content. Web 2.0 websites have altered the way data is communicated and distributed. Web 2.0 emphasizes the following:

Examples of Web 2.0 social media include:

else:#defining else block

   if x > 0:#defining if that checks x value greater than 0

       print(x, " is positive")#print value with message

   else:#defining else block

Output:

Please find the attachment file.

Explanation:

In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.

In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.

In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.

Explanation:

First I created a for loop with a "positionInUsernameArray" and singed it a value of 0. Next I stated while positionInUsernameArraywas less than or equal to arrUsername.Length - 1, positionInUsernameArraywould increment.

Once the base for loop was in place I created two if statements. The first if statement determines if positionInUsernameArray is equal to arrUsername.Length, if so, the for loop breaks and the method returns false. The second if statement determines if the parameter is equal to the position in the arrUsername array, if so, the method would return true, otherwise the for loop will restart.

For the "VerifyPassword" method, I used the same method as "VerifyUsername" just I changed the variable names.

the output is:

50 60 75

The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.

a. it designs its own applications but doesn't customize the operating system.

Explanation:

Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.

Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.

Cloud computing comprises of three (3) service models and these are;

1. Infrastructure as a Service (IaaS).

2. Software as a Service (SaaS).

3. Platform as a Service (PaaS).

Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.

The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.

Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).

Some of the advantages of Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.

Basically, platform as a Service (PaaS) providers (vendors) usually provide their clients (software developers) with server and data storage, operating system, data center, networking resources, etc., while the software developers design, deploy and manage their software applications.

Hence, a business should choose the platform as a service (PaaS) cloud model when it designs its own applications but doesn't customize the operating system.
