Procedure: 1. Create a folder named LastName_FirstName in your local drive. (ex. Reyes_Mark) 2. Using NetBeans, create a Java project named StudentList. Set the project location to your own folder. 3. Import Scanner, Map, and HashMap from the java.util package. 4. Create an empty hash map named students. 5. The output shall: 5.1. Ask three (3) of your classmates to enter their student number (key) and first name (value). 5.2. Display the keys and values of the map. 5.3. Delete the mapping of the third entry. 5.4. Enter your student number and first name. This would be the new third entry. 5.5. Display the entries in separate lines. 6. Create a Python script that meets the same specifications. Feel free to use lists to store input. 7. Save the script as student_list.py to your folder. Sample output: Enter student number 1: 2018-0004 Enter first name 1: Mark Enter student number 2: 2018-0017 Enter first name 2: Nika Enter student number 3: 2018-0134 Enter first name 3: Mairo Student…

To place a category, press the item in the answer box, then press the box under the corre- sponding category. benefits Add an answer item! Answer Bank risks Add an answer item! You can refer back to information you read earlier. You can see which search result links you have not yet pressed. A friend may see an embarrassing web search. A family member may see an ad for a gift you secretly bought for them. A related search will auto-complete so you do not need to type the whole thing. Someone with access to search cata could create a scam related to your interests.

There are three examples of when the main key of a link needs to be replaced with a replacement key.

hi I was just wondering if there is a different way instead of using Hash because I don't believe we learned that just yet. thank you!

Q3: Jami is an intern on a sales team at a large insurance company. On the first day of the internship, Jami is asked to download a list of all of her friends and contacts from Facebook and upload them to the company database. The team lead explains "This database keeps track of all of our employees, and well as their customers and prospects.

Jami is wondering if there are ethical issues she should be concerned about. Do you think there are ethical issues involved with this situation? If yes- what are those issues, specifically, and how would you advise Jami?

In your initial post, describe the function of hashing tools you can use to verify that two files are identical. For example, you can compare the hash value of a file on a website with the hash value of that file after you download it. If the hash values match, you downloaded the unmodified version of the website file. Research and discuss at least two examples other than the one provided.

How can you erase data that your JavaScript commands have stored in local storage? a. No action is necessary; this data will be erased automatically when the user closes the browser window or tab. b.

Make a php web page that uses a cookie to keep track of how many times a uses has viewd the page. The first time a particular user looks at the page, it should print something like "Number of views: 1." The second time the user looks at the page, it should print "Number of views: 2", and so on. Also, it prints out a special message on the 5th, 10th and 15th time the user looks at the page. And modify it so that on the 20th time the user looks at the page, it deletes the cookie and the page count starts over.

Create a webpage A2-Task2.html. The webpage is displaying one image. Each time the user moves the mouse out of the image, the image is changed to another one and one more 'sun' emoji is displayed under the image. When the number of 'suns' reaches seven (7), all 'suns are deleted (reset) and start to be displayed again. For example, the 8th time user moves the mouse out of the image, one 'sun' is shown, the 9th time - two 'suns', and so on. Note: - You should use two images. Each time the user moves the mouse out of the image, the image is changing. If an image of "Winter" is displayed it will change to "Summer", and opposite, if an image of "Summer" is displayed it will change to "Winter". The special character code for the 'sun' is "☀". Put the source code of your website A2-Task2.html here. Make sure you also upload the A2-Task2.zip of all files below.

Create struct HashNode and class HashTable that will be used to store students' data. For each student, it'll store the ID (string) as the key, and the first name (string), last name (string), and email (string) as the value. You can imagine a single HashNode as follows: "123456789" "Jessica" "Wolf" "abcdef@bartleby.com" HashTable should have the following attributes and methods: Attributes 1. The dynamic array that stores the data. 2. The number of elements currently stored. 3. The maximum number of elements the container can store. Methods 1. Constructor that takes from the user the maximum size of the container. 2. void insert(string ID, string firstName, string lastName, string email): uses the following hash function h2(h1(ID)) to map the key to a specific index in the table: • h1(ID): ww IDLength -1 Σ ID • h2(K) -> [0, N-1], where N is the table size In case the index that the hash function generated was already full, the insert function should add the student information in a…

Create a website for searching information regarding plants using Node JS and Mongo DB. The user should be able to search the plants using their local name or scientific name. The plant details with names in different local languages, scientific names, pictures of the tree/plant and its flowers are displayed. The website also should support search based on partial scientific or common name and all the plant names that match the result should be displayed as a hyperlink and on clicking the hyperlink the entire details of the plant should be displayed. The website also should provide search based on different types of plants such as flowering plants, vegetable/fruit plants trees, ornamental, medicinal or any other types. If the user clicks on search without clicking any of the buttons, they display all the plant details as an HTML table.
