Suppose you have a sentineled, doubly-linked list class as specified in project 2 and an object of that class called my_list. The function below finds and returns the first index of a specified value in that list, but portions have been removed. Using the minimum possible spacing at all in your answers, fill in the missing code. This algorithm does not employ the __iter__ and __next__ methods of the Linked_List class. Also note that this exercise does not include the object names, so your answers should include my_list. as appropriate. Finally, none of your responses should contain colons. As a reminder, the linked list implementation provides the following methods: insert_element_at(value, index) #cannot be used to append
append_element(value)
get_element_at(index)
remove_element_at(index)
__len__ #support for the len method to obtain the list's size
def index_of(my_list, val):
for k in :
if :
raise ValueError
and what is the performance?
Answers
Answer:
def index_of (my_list, val):
for k in range(my_list.__len__):
if my_list.get_element_at(k) == val :
return k
Explanation:
The python function "index_of" accepts two arguments, a list and the value to be searched for.
The for-loop iterates over the list using the "__len__" magic method to return the index of the searched term in the list if present.

The values of c₁, c₂, and c₃ create these distinct scenarios. If c₁ is correct, only the first case will prevail regardless of the values of c₂ and c₃.
There are four scenarios in which c₁ is false: (c₂ = T, c₃ = T), (c₂ = F, c₃ = T), and (c₂ = F, c₃ = F). The vulnerability occurs in the final scenario.
The different possible execution sequence are:(i) 16, 17, 18, 19, 31, 32, 33, 34
(ii) 16,17, 20, 21, 27, 31, 32, 33, 34
(iii) 16, 17, 20, 21, 27, 28, 31, 32, 33, 34

(vi) 16, 17, 20, 21, 22, 23, 24, 27, 28, 31, 32, 33, 34
(a): Yes, the given code may contain the DBZ (division by zero) vulnerability.
(b): The vulnerabilities sequence is as follows: 16, 17, 20,21, 22, 23, 24, 27 ,28).

print( ‘You are’, age, ‘years old. ‘)
Answers
The output print(‘You are’, age, ‘years old.’) function is a useful tool for programmers looking to display a person's age as part of a string of text. It is a straightforward function that can be easily incorporated into a variety of Python programs.
The outputprint(‘You are’, age, ‘years old.’) is a Python function that outputs a string of text that includes the variable ‘age’. The function prints the phrase ‘You are’, followed by the value of the variable ‘age’, and ends with the phrase ‘years old.’ For example, if the variable ‘age’ is assigned the value of 25, then the output of the function would be ‘You are 25 years old.’
This function is commonly used in programs that involve age calculations or when displaying a person's age. It is a simple way to incorporate the value of a variable into a text string and output it to the console or screen.

explain health tips on using computer
Answers
Many of us sit in front of computers for the majority of the day. Eye strain, back, shoulder, and wrist aches are on the rise, which is not surprising. The disadvantage of having to lead a long-term sedentary lifestyle outweighs this benefit, though. You should avoid it because it can cause weight gain, back issues, and other health issues.
Follow these Health tips to help prevent health problems from computer:
1.) Use A Standing Desk:
Getting a different type of desk is a choice you might want to take into account. The human body was not designed to spend eight hours a day at a desk. This puts a lot of stress on your body and may have a bad impact on your health.
2.) Get Up And Move Around Regularly:
The primary health issues caused by prolonged computer use are a result of the inactivity and lack of movement. You should therefore make it a point to get up and move around frequently to counteract this. You can even set your phone's alarm to sound every hour.
3.) Give Your Eyes A Break From Computer:
You might not be aware of it, but staring at a computer screen all day can be very taxing on your eyes. While a computer screen doesn't have a particularly bright light, you are staring into it for hours on end.
Your eyes may experience a great deal of strain as a result, which over time may result in headaches, vision issues, and other health issues.
4.) Keep Healthy Snacks Around Your Desk:
A physically demanding job is not sitting at a computer all day. It implies that while you are sitting and typing on a keyboard, you are not burning many calories.
So the last thing you want to do is make things worse by constantly snacking on unhealthy food. Eating foods that are heavily processed and high in calories, sugar, and fat will only exacerbate the health issues brought on by a sedentary job.
5.) Keep Your Desk Clean:
Many people aren't even aware of one of the most prevalent issues with a desk job that requires you to spend the entire day in front of a computer.
What problem is that? Bacteria.

Answers
Answer:
Here is the function same_person that takes two instances of Person as arguments i.e. p1 and p2 and returns True if they are the same Person, False otherwise.
def same_person(p1, p2): #definition of function same_person that takes two parameters p1 and p2
if p1.GTID==p2.GTID: # if the two instances of Person have same GTID
return True #returns true if above condition evaluates to true
else: #if the two instances of Person do not have same GTID
return False #returns false when two persons have different GTID
Explanation:
person1 = Person("David Joyner", 30, 901234567) #first instance of Person
person2 = Person("D. Joyner", 29, 901234567) #second instance of Person
person3 = Person("David Joyner", 30, 903987654) #third instance of Person
print(same_person(person1, person2)) #calls same_person method by passing person1 and person2 instance of Person to check if they are same
print(same_person(person1, person3)) #calls same_person method by passing person1 and person3 instance of Person to check if they are same
The function works as follows:
For function call print(same_person(person1, person2))
The GTID of person1 is 901234567 and that of person2 is 901234567
If condition if p1.GTID==p2.GTID in the function same_person checks if the GTID of person1 is equal to the GTID of person2. This condition evaluates to true because GTID of person1 = 901234567 and GTID of person2 = 901234567
So the output is:
True
For function call print(same_person(person1, person3))
The GTID of person1 is 901234567 and that of person3 is 903987654
If condition if p1.GTID==p2.GTID in the function same_person checks if the GTID of person1 is equal to the GTID of person3. This condition evaluates to false because GTID of person1 = 901234567 and GTID of person2 = 903987654 and they are not equal
So the output is:
False

Further, let's suppose that despite the bucolic setting, the residents of all these houses are avid cell phone users.

Give an efficient algorithm that achieves this goal, using as few base stations as possible.

A denial-of-service (DoS) attack is a type of cyber attack in which an attacker attempts to make a computer or network resource unavailable to its intended users. This is typically accomplished by overwhelming the target with traffic, requests for resources, or other types of communication until the system is unable to function properly. DoS attacks are often launched using a network of compromised computers, or "bots," that are controlled by the attacker and used to generate large amounts of traffic.
The goal of a DoS attack is to disrupt normal traffic and prevent legitimate users from being able to access the targeted system or resource. DoS attacks can be carried out by a single individual or a group of attackers, and they can target a wide range of systems, including websites, online services, and networks.
