Instructions
Redo Programming Exercise 6 of Chapter 8 using dynamic arrays. The instructions have been posted for your convenience.
The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:
TFFTFFTTTTFFTFTFTFTT
Every other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:
ABC54301 TFTFTFTT TFTFTFFTTFT
indicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9 (note the empty space). The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID,…
flip_matrix(mat:list)->list
You will be given a single parameter a 2D list (A list with lists within it) this will look like a 2D matrix when printed out, see examples below. Your job is to flip the matrix on its horizontal axis. In other words, flip the matrix horizontally so that the bottom is at top and the top is at the bottom. Return the flipped matrix.
To print the matrix to the console:
print('\n'.join([''.join(['{:4}'.format(item) for item in row]) for row in mat]))
Example:
Matrix:
W R I T X
H D R L G
L K F M V
G I S T C
W N M N F
Expected:
W N M N F
G I S T C
L K F M V
H D R L G
W R I T X
Matrix:
L C
S P
Expected:
S P
L C
Matrix:
A D J
A Q H
J C I
Expected:
J C I
A Q H
A D J
A "generic" data structure cannot use a primitive type as its generic type.

- (Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forwardData structures find_color(colors:set, values:list) -> list The function will have two parameters. The first parameter is a set of strings known as Colors. A second parameter is a list of tuple-2 known as Values. Colors will contain a set of randomly selected colors. Values will contain a list of tuples of size 2. Each tuple will contain color (str) and a number (int). The function should look at each tuple in Values. For each tuple, add the number (the second value in the tuple) to a list of numbers if the color in the tuple (the first value in the tuple) is in Colors. In other words, find all tuples that have a color in the Colors and add the tuples numbers to a list. Finally, the function should return the list of numbers collected in the order they are found in the values list. Example: Colors: {'black', 'pink', 'yellow'} values: [('green', 100), ('yellow', 13), ('red', 6)] Expected: [13] Colors: {'yellow'} values: [('black', 54), ('pink', 5)] Expected: [] Colors: {'black',…arrow_forwardPython please! Generalized image blender function Create a function blend images() which takes multiple RGB images as an input, and outputs a blended image. The function should accept following parameters 1. image list- A Python list of 3D arrays where each 3D array corresponds to an RGB image 2. weight list-A Python list of float values between (0, 1) corresponding to the pixel weight to be given to each image-e.g. [0.2, 0.3, 0.1, 0.4] for 4 images. The sum of the weights should be equal to 1. Test your function against a provided list of 5 images with following weight lists (i.e. 2 blended images) [0.2, 0.2, 0.2, 0.2, 0.2]- blend all 5 images [0.2, 0.3, 0.5]- blend first 3 images NOTE: DO NOT USE pre-existing image blending functions.arrow_forward

The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item.

You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .arrow_forward
