In Python please.
Alice travels a lot for her work. Each time she travels, she visits a single city before returning home.
Someone recently asked her "how many different cities have you visited for work?" Thankfully Alice has kept a log of her trips. Help Alice figure out the number of cities she has visited at least once.
Input:
The first line of input contains a single positive integer T <_ 50 indicating the number of test cases. The first line of each test case also contains a single positive integer n indicating the number of work trips Alice has taken so far. The following n lines describe these trips. The ith such line simply contains the name of the city Alice visited on her i th trip.
Alice's work only sends her to cities with simple names: city names only contain lowercase letters, have at least one letter, and do not contain spaces.
The number of trips is at most 100 and no city name contains more than 20 characters.
Output:
For each test case, simply output a single line containing a single integer that is the number of distinct cities that Alice has visited on her work trips.
Answers
Answer:
Explanation:
We have the following
t is the number of test cases.
n is the number of trips for each testcase
name is the name of the city
all the unique names are added to the list and at last the length of the list is printed.
The program is written as follows
t = int(input) - for i in range(t): n = int(input) 1 = [] for j in range(n): name = input if name not in l: 1.append(name) pr
t = int(input())
for i in range(t):
n = int(input())
l = []
for j in range(n):
name = input()
if name not in l:
l.append(name)
print(len(l))
Output:
The program illustrates the use of lists.
Lists in Python are used to store several values on one variable.
The program written in Python where comments are used to explain each line is as follows
#This gets input for the number of test cases
T = int(input())
#This iterates through the test cases
for i in range(T):
#This gets input for n; the number of work trips
n = int(input())
#This creates a list of the cities visited
city = []
#This iterates through the work trips
for j in range(n):
#This gets the name of the city
name = input()
#For names not in the list of city
if name not in city:
#The city is appended to the city list
city.append(name)
#This prints the number of cities
print(len(city))

The POLYNOMIAL ADT (Abstract Data Type) is a mathematical concept used to represent polynomials, which are expressions consisting of variables and coefficients, combined using addition, subtraction, and multiplication.
What does this do?The POLYNOMIAL ADT defines operations that can be performed on polynomials, such as evaluating the polynomial at a specific value, adding, subtracting, multiplying, and differentiating polynomials.
Here are the descriptions of the operations defined in the POLYNOMIAL ADT:
Evaluate()(xp, z): This operation takes a polynomial xp and a value z, and evaluates the polynomial at the point z. It returns the result of the evaluation.
Add()(1xp, )(2xp): This operation takes two polynomials, 1xp and 2xp, and returns a new polynomial that results from adding the two polynomials.
Subtract()(1xp,)(2xp): This operation takes two polynomials, 1xp and 2xp, and returns a new polynomial that results from subtracting 2xp from 1xp.
Multiply()(1xp,)(2xp): This operation takes two polynomials, 1xp and 2xp, and returns a new polynomial that results from multiplying the two polynomials.
Differentiate()(xp): This operation takes a polynomial xp and returns a new polynomial that results from differentiating xp. The resulting polynomial has one less degree than the original polynomial and represents the derivative of the original polynomial.
These operations provide a powerful way to manipulate and analyze polynomials mathematically. The POLYNOMIAL ADT is used in various fields, such as physics, engineering, and computer science, where polynomials are often used to model real-world phenomena.

Answers
Answer: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.

What happens after the POST?
Answers
After the POST, the computer is ready for user interaction. Users can launch applications, access files, browse the internet, and perform various tasks depending on the capabilities of the operating system and the installed software.
After the POST (Power-On Self-Test) is completed during a computer's startup process, several important events take place to initialize the system and prepare it for operation. Here are some key steps that occur after the POST:
1. Bootloader Execution: The computer's BIOS (Basic Input/Output System) hands over control to the bootloader. The bootloader's primary task is to locate the operating system's kernel and initiate its loading.
2. Operating System Initialization: Once the bootloader locates the kernel, it loads it into memory. The kernel is the core component of the operating system and is responsible for managing hardware resources and providing essential services.
The kernel initializes drivers, sets up memory management, and starts essential system processes.
3. Device Detection and Configuration: The operating system identifies connected hardware devices, such as hard drives, graphics cards, and peripherals.
It loads the necessary device drivers to enable communication and proper functioning of these devices.
4. User Login: If the system is set up for user authentication, the operating system prompts the user to log in. This step ensures that only authorized individuals can access the system.
5. Graphical User Interface (GUI) Initialization: The operating system launches the GUI environment if one is available. This includes loading the necessary components for desktop icons, taskbars, and other graphical elements.
6. Background Processes and Services: The operating system starts various background processes and services that are essential for system stability and functionality.
These processes handle tasks such as network connectivity, system updates, and security.

statement. SECOND, create a truth table based on the circuit/statement. (20 pts. each for statement and

Answers
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.
Given the logical circuit, we are required to perform two actions on it. Firstly, convert the circuit into a logical statement. Secondly, create a truth table based on the circuit/statement. Let's understand how to do these actions one by one:Conversion of Circuit into Logical Statement.
The given circuit contains three components: NOT gate, AND gate and OR gate. Let's analyze the working of this circuit. The two input variables A and B are first passed through the NOT gate, which gives the opposite of the input signal.
Then the NOT gate output is passed through the AND gate along with the input variable B. The output of the AND gate is then passed through the OR gate along with the input variable A.We can create a logical statement based on this working as: (not A) and B or A. This can also be represented as A or (not A) and B. Either of these statements is correct and can be used to construct the truth table.
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
In the truth table, we have all possible combinations of input variables A and B and their corresponding outputs for each component of the circuit.
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.
