In this project, you will create a tool that will help a company print invoices and keep track of the total
amount it has billed and the total amount it has discounted.
Imagine the company has a regularly scheduled billing process. Perhaps every week, it prints invoices
that it uses to communicate to the customer what the customer owes them for the purchases they
made.
Suppose that the company has two types of customers:
retail and corporate.
The discount schedules for
these two types of customers differ. For retail customers,
If the bill is greater than
or equal to
$500, they get a 20% discount
If the bill is greater than
or equal to
$250 but less than $500 they get a 10
% discount
Otherwise, they don
’
t get a discount.
For corporate customers,
If the bill exceeds
or is equal to
$1,000 they get a 30% discount
If the bill exceeds
or is equal to
$500 but is less than $1,000, they get a 20% discount
Otherwise, they don
’
t get a
discount.
Suppose further that the company only sells in the states of Illinois, Indiana, and Wisconsin. The
company must assess the correct sales tax based on the state. If the customer is in Illinois (abbreviated
IL), the sales tax is 8.75%. If the cust
omer is in Wisconsin (WI), the sales tax is 8.25%. And if the customer
is in Indiana (IN), the sales tax is 8.5%.
Your program must repeatedly ask the user to enter invoice data. Specifically, your program will ask the
user to enter the cost of the purchas
e, the type of customer, and the state where the customer is
located. Based on that, it will print a summary that shows the purchase cost, the sales tax collected, the
amount of the discount, and the final price. Your program will continue doing this as lo
ng as the user
indicates they have more invoices to enter.

My assignment is -
"given 2 images , you have to classify that is written by same person or not if it is same person then output will be 1 else output will be 0".
For that problem
I have one folder of dataset . In that folder(dataset) I have 1352 of subfolders, each subfolder define different person's handwritting. each folder have 4 or 5 or 6 handwritting of that person.
so make a model from scratch , how to read folder and how to make the model .
okay ?
Is that problem is clear for you , if you have any question tell me?

Imagine that you are the founder of a new ambitious startup "Social Network: Friends", which proposes to organize the search for new friends by comparing tastes in the field of cinema. Each user registering on the portal is asked to complete a very simple questionnaire. It consists of N films, for each of which one of two ratings is required: 1 if the user can say that he likes the specified film, and 0 otherwise (if he does not like it or the user has not watched it).
After filling out the questionnaire, the user receives a list of the most suitable for him in terms of cinematic compatibility.
Your task is to write the friendadviser class, within which to implement the following methods:
The fit(self, R) method, which takes as input a matrix R of dimension 𝑀×𝑁 , where 𝑀 is the number of registered users of your social network, and 𝑁 is the number of films in the questionnaire. Matrix element 𝑟𝑖𝑗 is a mark put by the user 𝑖 in the questionnaire opposite the movie 𝑗 .
_sim(u1, u2) - a function that calculates the similarity (frequency score based on the PMI metric) of users 𝑢1 and 𝑢2 by their rating vectors. We recommend using a "truncated" version of PMI, which is called score in the lecture.
U_idx(u0, alpha) - a function to find a set of registered users (namely, their indexes) whose tastes are similar to the new user 𝑢0 at least as high as alpha.
find_friends(u0, how_many) is a function that finds new friends for user 𝑢0 in the number specified by the how_many argument. At the output, we expect to get an array with the indices of such friends. For the sake of convenience, return the indexes in descending order of similarity of interests.
import numpy as np
class friendadviser(object):
def fit(self, R: np.array):
self.R = R
self.n_users = R.shape[0]
self.n_items = R.shape[1]
def_sim(self, u1: np.array, u2: np.array):
#PMI
freq = (np.dot(u1, u2.T) + 1) / (np.sum(u1) + np.sum(u2) - np.dot(u1, u2.T) + 1)
pmi = np.log2(freq) - np.log2(np.sum(freq))
score = np.sum(pmi[pmi > 0])
return score
def U_idx(self, u0: np.array, alpha: float):
sim_scores = []
for i in range(self.n_users):
if i != 0:
sim_score = self._sim(u0, self.R[i])
if sim_score >= alpha:
sim_scores.append((i, sim_score))
sim_scores.sort(key=lambda x: x[1], reverse=True)
return [x[0] for x in sim_scores]
def find_friends(self, u0: np.array, how_many: int):
similar_users = self.U_idx(u0, 0)
return np.array(similar_users[:how_many])
Notes:
Return the result as np.array. If list is used, validation errors may occur.
In this task, it is forbidden to use the pandas and sklearn libraries.

The script needs to perform the following functions:
It needs to solve simple ONE letter captcha.
1. Open a browser, in my case chrome.
2. Access the site "narutoplayers.com.br/np2/?p=login", but DO NOT LOGIN, WAIT UNTIL THE USER LOGINS.
3. Wait until the user is on the "https://www.narutoplayers.com.br/np2/?p=news" page.
4. Once logged in, click on the text "Hunts" to be redirected to another page.
5. Search for a specific field to make a select.
6. Select the text containing the word "Student".
7. Click to search.
8. Read the image that has a text and write the letter that the text contains in a specific field just below the image.
10. Click to search again.
11. The program should have a timer of 300s.
12. The program should repeat all actions, except for opening the browser and logging in.
13. The browser should not be closed in this process.
Divide the code into 10 or more parts as needed for the desired solution.

Write a version of the Fast Fourier Transform (fft) for the case where n is a power of 3, dividing the input vector into three subvectors, solving the problem recursively on them, and combining the solutions of the subproblems. Write the recursive relation for the execution time of the program and solve the recursive relation by the central theorem.

Make this script.
The script needs to perform the following functions:
It needs to solve simple ONE letter captcha.
1. Open a browser, in my case chrome.
2. Access the site “narutoplayers.com.br/np2/?p=login”, but DO NOT LOGIN, WAIT UNTIL THE USER LOGINS.
3. Wait until the user is on the “https://www.narutoplayers.com.br/np2/?p=news” page.
4. Once logged in, click on the text “Hunts” to be redirected to another page.
5. Search for a specific field to make a select.
6. Select the text containing the word “Student”.
7. Click to search.
8. Read the image that has a text and write the letter that the text contains in a specific field just below the image(THE CAPTCHA IS IN THE CAPTCHA.PHP).
10. Click to search again.
11. The program should have a timer of 300s.
12. The program should repeat all actions, except for opening the browser.
13. The browser should not be closed in this process.
Thanks

This is my code for a chess game. As you can see it uses the library of vector which is object oriented programming. Can you remove this vector and all the concepts of object oriented programming in the code and provide me with a new code.

In some applications we want to find minimum spanning trees with specific properties. The next problem is an example.
Input: undirected graph G = (V, E), edge weights we, and a subset U of nodes.
Output: the minimum spanning tree in which the nodes of the set U are leaves. (The tree may have leaves from nodes of the set V - U as well).
Write pseudocode for an algorithm for the above problem which runs in time O( |E| log|V| ). How can we find a maximum spanning tree instead of
minimum spanning tree?

The purpose of this program is to retrieve, format, and print the shell environmental variables for the user running the program. The program will:
only execute commands if execution occurred as a result of this program name being called and not when imported
when imported, functions will only execute when called
create a function called main that will call the other functions to perform the required actions
create a function called retrieve_env_variables
retrieve the environmental variables with associated values
return the variable name with associated value
create a function called format_env_variables
formats the key/value pairs
environmental variable name left justified within a 30 character string
value formatting does not change
create a function called print_env_variables
prints the formatted environmental variable
followed directly by a colon and a space
followed directly by the value that the environmental variable holds
end the line with one new line

Write a user-defined MATLAB function that calculates the determinant of a square (𝑛 x 𝑛) matrix, where
𝑛 can be 2, 3, or 4. For function name and arguments, use D = Determinant(A). The input argument 𝐴 is
the matrix whose determinant is calculated. The function Determinant should first check if the matrix is
square. If it is not, the output 𝐷 should be the message “The matrix must be square.”

The infinite series 𝑓(𝑛) = ∑ (1 /𝑖^4)
𝑖=1 converges to the value of 𝜋^4/90 as 𝑛 approaches infinity. You are
provided with two files: one of them contains 10,000 16-digit (or double) precision values, and the other
contains the same values but now in 8-digit (or single) precision. Note that the values are needed for
computing the given summation for 𝑛 = 10,000, but they have been randomly shuffled.
a) Write a MATLAB script to compute the summation of the 10,000 shuffled values using single
precision floating point numbers.
b) Repeat the computations in a) but first sort the values in ascending order.
c) Repeat a) and b) except now using the double precision floating point values.
d) Compute the true percent relative errors of the four different results against the theoretical true
value for the infinite series.
e) Repeat a, b, c, d, but now using in-built sum()MATLAB function and investigate the results.
f) What type of numerical error does this question illustrate? What is a viable remedy (or what are
viable remedies) to this type of numerical error?

In some applications we want to find minimum spanning trees with specific properties. The next problem is an example.
Input: undirected graph G = (V, E), edge weights we, and a subset U of nodes.
Output: the minimum spanning tree in which the nodes of the set U are leaves. (The tree may have leaves from nodes of the set V - U as well).
Write pseudocode for the above problem which runs in time O( |E| log|V| ). How can we find a maximum spanning tree instead of
minimum spanning tree?
