Write code that swaps the first and last elements in a list called my_list. Assume that the list has already been created and contains at least one element.
Answers
my_lst = ([1,2,3,4,5,6])
h = my_lst[0]
my_lst[0] = my_lst[-1]
my_lst[-1] = h
print(my_lst)
The code that swaps the first and last elements in a list called my_list is as follows:
my_list = ["break", 14, 15, "john", "black"]
my_list[0], my_list[-1] = my_list[-1], my_list[0]
print(my_list)
Code explanation:The code is written in python.

Write a recursive function called sum_values that takes in a list of integers and an index of one element in the list and returns the sum of all values/elements in the list starting with the element with the provided index and ending with the last element in the list.
Answers
Answer:
Explanation:
The following code is written in the Java programming language and actually takes in three parameters, the first is the list with all of the int values. The second parameter is the starting point where the adding needs to start. Lastly is the int finalSum which is the variable where the values are all going to be added in order to calculate a final int value. Once the recursive function finishes going through the list it exits the function and prints out the finalSum value.
public static void sum_Values(ArrayList<Integer> myList, int startingPoint, int finalSum) {
if (myList.size() == startingPoint) {
System.out.println(finalSum);
return;
} else {
finalSum += myList.get(startingPoint);
sum_Values(myList, startingPoint+1, finalSum);
}

Answer:
Software as a Service (SaaS)
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. Platform as a Service (PaaS).
2. Infrastructure as a Service (IaaS).
3. Software as a Service (SaaS).
Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.
Hence, Software as a Service (SaaS) is an example of a cloud computing environment that provides users with a web based email service. Therefore, if you pay a subscription fee to use an application via the internet rather than purchasing the software outright, the app is called a Software as a Service (SaaS) application.
Some examples of SaaS applications are Salesforce, Google apps, Bigcommerce, Dropbox, Slack etc.

c. when the speed of the compression algorithm fastest.
d. even when the system has faster SSDs.
Answers
Answer:
d. even when the system has faster SSDs.
Explanation:
Given that Memory compression and Paging are both means of performing memory management in different ways.
However, Memory compression is a useful alternative to paging "even when the system has faster SSDs."
This is because Memory compression enhances the productivity of Radom Access Memory, RAM, which in turn increases the performance level of a computer.
Also, paging requires consistent writing on Disks, which has been found to degrade disks most especially solid-state drives, SSDs.

Display all the lines in unixPasswd that contain at least 10 consecutive lowercase letters. How many names are there in total that meets this criteria?
Answers
Answer and Explanation:
To display 10 consecutive lower case letters in Unix, we make use of the commands below. The first command finds the letters in the file and the second command counts them line by line.
$ grep '[a-z]\{10,\}' /unixPasswd/passwd
# this command displays lines with at least 10 consecutive lowercase letters or more than 10 consecutive lowercase letters
$ grep '[a-z]\{10,\}' /unixPasswd/passwd | wc -l
# this command counts the number of lines that has at least 10 consecutive lower case letters or more than 10 consecutive lowercase letters
Note: the unixPasswd is a file in passwd file. The # is used when we want to add comments, is optional here. The $ is a prompt on the terminal that begins a new command.

triple Data Encryption Standard (DES)
Explanation:
Sincerely : Baby weeb
A company wants to transmit data over the telephone, but they are concerned that their phones may be tapped. All of their data is transmitted as four-digits. They have asked you to write a program that will encrypt their data so that it may be transmitted more securely. Your program should read a four-digit integer and encrypt it as follows: 1. Replace each digit by (the sum of that digit and 3) modulus 10. Then 2. Swap the first digit with the third, and swap the second digit with the fourth. 3. Print the encrypted integer.
Answers
Answer:
def encrypt_digit(digit):
if type(digit) is int or float:
digit = str(digit)
hold = list()
for x in digit:
d = str((int(x) + 3)%10)
hold.append(d)
first = hold.pop(0)
second = hold.pop(0)
third = hold.pop(0)
fourth = hold.pop()
print(int("".join([third,fourth, first, second])))
encrypt_digit(7836)
Explanation:
The python function accepts a four-digit parameter which represents the data transmitted over the company's telephone network. The function encrypts the data by adding 3 to each digit and getting the modulus of division 10, then the digits are swapped and printed out encrypted and ready for transmission.
Encryption are used to protect data and files when they are is being transmitted
The encryption program written in Python, where comments are used to explain each line is as follows:
#This gets input for the number
num = int(input())
#This converts the number to string
digit = str(num)
#This creates a list
myList = list()
#This encrypts the number, and add the numbers to a list
for i in digit:
d = str((int(i) + 3)%10)
myList.append(d)
#This prints the result of the encryption
print(int("".join([myList[2],myList[3], myList[0], myList[1]])))

Answers
Answer:
<textarea wrap="hard" cols="30" rows="5"></textarea>
Explanation:
A textarea element or tag is a form tag element of a HTML file. It is used to ask for input value from a user in a webpage. The textarea tag has an opening and a closing tag.
The 'cols' attribute is used to set the column length while the 'rows' attribute sets the row length of the textarea element. The 'wrap' attribute has three options namely; soft, hard, and off. 'soft' adds the textarea wrapping, 'hard' sets off the box wrapping but only wraps each line, while the 'off' option removes all wrapping in the tag.
