Write use case narratives for the two use cases with highest implementationpriorities. **Case Study for OLX**Read carefully the following problem statement/case study and answer the questions below:---**OLX** is an online platform where Buyers meet Sellers, i.e., people advertise the items to be sold and the interested people contact sellers to buy the item. Any person can see the current selling items in the catalog, but in order to advertise a new item, one has to register first. If a user already has an account, he could log in simply by adding email and password.In the case of an unregistered user, you have to provide email, password, and verify password. After registration, one can post a free advertisement by giving the details of the item to be sold (Ad title, Category, Ad Description, Price, Photo, etc.). For contact, he could provide his name, email, phone (available at WhatsApp), and state he belongs. One may edit or delete his advertisements. Could check responses to his ads and could see saved ads.Any person can search for a specific item by name; he can narrow down the search by mentioning the preferred city, giving the price range e.g., minimum 500,000/maximum 800,000. A person can also check messages and settings in his/her account.

Your understanding of importing modules, using lists and dictionaries and creating objects from a class will be exercised in this lab. Be prepared to use your solution for the “Classes” lab (see Blackboard for the link) where you wrote the PlayingCard class. In this lab, you will have to generate a random list of PlayingCard objects for where the suit and rank combinations of each card are randomly choosen. Using this list of randomly created playing cards, you will use dictionaries and lists to store important data about these playing cards, particularly the frequency distribution of each rank-suit combination you created (e.g. like if 10 queen of hearts cards are generated and counted.) Thanks to the clearly described interface used to communicate to any PlayingCard object, specifically the get_rank() and get_suit() methods, you can just import your “Classes” lab as a module and use your previously written code! Note: You’ll definitely need to make sure your solutions work for this…

You will be using on RV related review comments to train a Sentence completion model. You could use the code below. The code is written in Jupyter notebook python. please follow the following instructions: 1. Build a working sentence completion model. Training data is provided in train.csv. This model should take partial sentences (e.g., "hey how ar," "hello, please") and provide completion for that sentence. Not every input needs to be completed into a correct sentence (e.g., "asdfauaef" does not need to have a sentence completion). For this model's purposes, a sentence is considered completed if an "end of sentence" character (like a full stop, question mark, etc.) occurs within the next five words OR. We predict up to 5 words from the input. 2. BONUS: If you use word vectors or other techniques from what we shared in class using character encoding and have a working model. 3. The test data (test.csv) will be used to evaluate the model. The test file contains partial sentences. Use…
