Scenario: You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
Complete this Javascript file. NOTE: Use the API endpoints available at https://jsonplaceholder.typicode.com/ to get the data required in these exercises. // HINT: Read the documented Resources and Routes. Also the guide: https://jsonplaceholder.typicode.com/guide/ 3) Create a function named "getComments". This function needs to accept a "postID" parameter. Use Fetch with Async/Await to request all the comments for the postID that is passed in as a parameter. The function should return all the comments for the requested postID as JSON data. 4) Create a function named "getUser". This function needs to accept a "userID" parameter. Use Fetch with Async/Await to request the data for the requested user. The function should return JSON data. 5) Create a function named "getTodosForUser". This function needs to accept a "userID" parameter. Use Fetch with Async/Await to request all of the todos for the requested user. The function should return JSON data.

astfoodStats Assignment Description For this assignment, name your R file fastfoodStats.R For all questions you should load tidyverse, openintro, and lm.beta. You should not need to use any other libraries. suppressPackageStartupMessages(library(tidyverse)) suppressPackageStartupMessages(library(openintro)) suppressPackageStartupMessages(library(lm.beta)) The actual data set is called fastfood. Continue to use %>% for the pipe. CodeGrade does not support the new pipe. Round all float/dbl values to two decimal places. All statistics should be run with variables in the order I state E.g., "Run a regression predicting mileage from mpg, make, and type" would be: lm(mileage ~ mpg + make + type...) To access the fastfood data, run the following: fastfood <- openintro::fastfood Create a correlation matrix for the relations between calories, total_fat, sugar, and calcium for all items at Sonic, Subway, and Taco Bell, omitting missing values with na.omit(). Assign the…
We will use the file classlist.txt. Note that it contains a list of usernames. 3. Write a script called finduser that is to be called as follows, where classlist is the name of the classlist file, and username is a particular student's username, either first name or last time. ./finduser classlist username The script should check that the correct number of arguments was received and print an error message if not, check whether the classlist file exists and print an error message if not, print the line of the given username in the classlist file If you have not been doing so all along, you should now add some comments to your script and thoroughly test it! 4. Write the script into your lab report.
In C#: Create a function that takes in one argument: The url to an API endpoint. The function should make the API call and pull the data in, convert it to a dictionary, and pull out the number of kills from the last 7 games the user played.

Create a javascript file and use it as script for the products.html page. In the script, create an empty array to store the items added to the cart. Create a products array and create a product object for each of your products from products.html and store it in the products array when the script loads. The script should have the following functions: Add - Takes an id, finds the product object in the products array and adds it to the items purchased array. Remove - Takes an id and removes the corresponding object from the items purchased array. Returns html for displaying the items in the cart. Existing code: products.html <!DOCTYPE html><html> <head><title>Products</title></head> <body><div><div><a href="Checkout.html"><span style="float:right"><p>(<span>0</span>) Cart</p></span></a></div><div class="product"><img src="img/clorox.jpg"><p class="price">Price:…
Question#4: Write a small program that has the "account_balance" as a global variable and the function "add_balance(float amount)". The function reads the current balance value, adds an amount to it (which is entered by the user) and writes the new value to the balance variable. After that, create 2 threads which will invoke the add balance(float amount) function and add different values. Run the program and make sure that the data is consistent (Use a proper lock on the variable).

create a script that will parse data from Rotten Tomatoes, a movie reviews website. The work you have to do is identical to what we covered in lectures 4 and 5, albeit for a different website. Please read and follow the instructions below very carefully. Step 1 Your script should begin by defining two variables (after importing libraries, etc) movie a string variable indicating the movie for which reviews will be parsed pageNum the number of review pages to parse For example, to parse the first 3 pages of the Gangs of New York reviews, set movie ‘’gangs_of_new_york” and pageNum = 3. Your code should go to the movie’s All Critics reviews page of rotten tomatoes, and parse the first three pages of reviews. Pagination on rotten tomatoes happens by clicking on the “Next” button.
