Campground reservations, part 3: Available campsites Excellent job! This next one's a little more challenging. Which campsites are available to reserve? We want to be able to quickly find which campsites are available. Can you help us? Given a campgrounds array, return an array with the campsite numbers of all currently unreserved (isReserved === false) campsites. Call the function availableCampsites. Dataset As a reminder, our data looks like this. It's an array with a bunch of campsite objects in it. Here is a small subset of the data to give you an idea: const campgrounds = [ { number: 1, view: "ocean", partySize: 8, isReserved: false }, { number: 5, view: "ocean", partySize: 4, isReserved: false }, { number: 12, view: "ocean", partySize: 4, isReserved: true }, { number: 18, view: "forest", partySize: 4, isReserved: false }, { number: 23, view: "forest", partySize: 4, isReserved: true }, ];
Integer num_rows is read from input, representing the number of rows of data remaining in the input. Two-dimensional list vals_2d consists of data read from the remaining input. Output each row of numbers in vals_2d on one line, ending each number with a space.

#If you're not sure how to start, look at the swap_red_blue and blur#examples below. #Problem A: Invert Colorsdef invert(img_matrix): ''' Purpose: Inverts the colors in an image by setting each color component to 255 minus its original value. Input Parameter(s): A 3D matrix (list of lists of lists) representing an .bmp image Each element of the matrix represents one row of pixels in the image Each element of a row represents a single pixel in the image Each pixel is represented by a list of three numbers between 0 and 255 in the order [red, green, blue] Return Value: A 3D matrix of the same dimensions, with the colors of each pixel inverted ''' #TODO: Finish this function

Args:feature_vector - A numpy array describing a single data point.label - The correct classification of the feature vector.current_theta - The current theta being used by the perceptronalgorithm before this update.current_theta_0 - The current theta_0 being used by the perceptronalgorithm before this update. Returns: A tuple where the first element is a numpy array with the value oftheta after the current update has completed and the second element is areal valued number with the value of theta_0 after the current updated hascompleted.
Using the data file below design a hierarchical struct to organize the data. Then declare an array of structs for the reservations. The data file contains ten reservations. There are 8 columns of data: party name, size, date and time for the reservation, phone number, email address, credit card number and expiration date for the credit card. The data can be read from the file below so you will not need to type it in repeatedly. Once you have populated the array with data perform the following tasks: Write a function that will print out to the screen the information for one reservation.In the main program write code that prompts the user to enter a date in the form MM DD YYYYCall the function to print out all reservations on that date. You can make a loop that calls the print function repeatedly or you can put that code inside the print function.TEST CASES: April 30, 2023 and May 12, 2023. In this example you need to carefully consider what data types to use. For example, the credit…
This code is a part of a C dictionary. Please write the code for the below requirements. dict_get Next, you will implement: char* dict_get (const dict_t* dict, const char* key); This function goes through the list given by dict. If you use the above structure, this means starting at el = dict->head and checking each time whether the key at el is key; if it is not, we set el = el->next, until either key is found, or we reach el == NULL. To compare key with el->key, we need to compare one by one each character in key with those in el->key. Remember that strings in C are just pointers (memory addresses) to the first character in the string, so comparing el->key == key will not do what you want. So how do you even get the length of a string s? You would start at memory location s and advance as long as the byte at s (i.e. *s) is not the end-of-string marker (\0, the NULL character). This can get a bit messy, so luckily, you are allowed to use the string comparison…
This section has been set as optional by your instructor. OBJECTIVE: Write a program in Python that prints the middle value of a dictionary's values, using test_dict from the test_data.py module. NOTE: test_dict is created & imported from the module test_data.py into main.py Example 1: test dict = {'a':1,'b':9,'c':2,'d':5} prints 5 Example 2: test_dict = {'b':9,'d':5} prints 5 Hint: You may(or may not) find the following function useful: list.sort() which sorts the elements in a list. Note: the result is automatically stored in the original list, and return value from the function is None Туре list = [1, 2,3,2,1] After calling: list = [1,1,2,2,3] list.sort(), 339336.2266020 x3zgy7 LAB 13.11.1: Middlest Value (Structured Types) АCTIVITY 0/11 File is marked as read only Current file: test_data.py 1 #This module creates the test_dict to be used in main.py 2 #Reads input values from the user & places them into test_dict 3 dict_size = int(input()) #Stores the desired size of test_dict. 4…
As part of this assignment, the program that you will be writing will store current grades in a dictionary using course codes as keys and with values consisting of percent grades in lists. The main functions of this program are to print a student's gradebook, to drop the lowest grade in each course, print the student's gradebook again, drop the course with lowest average, and finally printing the student's gradebook again. This program requires a main function and a custom value-returning function. In the main function, code these basic steps in this sequence (intermediate steps may be missing): start with an empty dictionary that represents a gradebook and then use a while loop to allow the input of course codes from the keyboard. End the while loop when the user presses enter without entering data.within the while loop:for each course entered, use a list comprehension to generate five random integers in the range of 70 through 100. These random integers in a list represent the…
