Super Ghost Project
Rule changes:
The premise of the game remains the same, there are two players adding words to a growing word fragment. Each player will take turns attempting to add letters to a growing word fragment. The letter you select should attempt to force your opponent to spell a word or create a word fragment that has no possibility of creating a word. Unlike the prior ghost competition, when it is your turn you are allowed to add a letter to either the front or back of the word fragment.
Winning Criteria:
If your opponent spells a word that is at least 6 characters long
if your opponent creates a word fragment that has no possibility of creating a word
if your opponent takes longer than 60 seconds to select a word.
Tip: If you are the first player you can only spell words that are odd length thus you can only lose when you spell words that are odd but you can win when your opponent spells words that are even length. Accordingly, if you are the first player you should…
Implement the "Add song" menu item. New additions are added to the end of the list. Ex:
ADD SONG
Enter song's unique ID: SD123
Enter song's name: Peg
Enter artist's name: Steely Dan
Enter song's length (in seconds): 237
What happens if you attempt to search up a value and the key in the map does not exist?

- Create an ArrayList of strings to store the names of celebrities or athletes. Add five names to the list. Process the list with a for loop and the get() method to display the names, one name per line. Pass the list to a void method. Inside the method, Insert another name at index 2 and remove the name at index 4. Use a foreach loop to display the arraylist again, all names on one line separated by asterisks. After the method call in main, create an iterator for the arraylist and use it to display the list one more time.arrow_forwardImplement the "Remove song" function.

- Gradient FillIn this labwork are asked to write a GUI application again using AWT. This is a fairly easy labworkthat is more about getting used to synchronized online learning. You are expected to:• Draw two rectangles.• Both of them should be filled using GradientPaint() function of AWT. (Check out itsfunction definition that is listed below.)• The first gradient should be parallel to the diagonal of the first rectangle. The colorgradient should not be repeated (acyclic).• The second gradient should be horizontal. The color gradient should be repeated forthis one (cyclic).• You are free to choose the colors but other than that your output should be similar tothe example screenshot given below.arrow_forward# Create Custom Transformer Create a custom transformer, just as we did in the lecture video entitled "Custom Transformers", that performs two computations: 1. Adds an attribute to the end of the numerical data (i.e. new last column) that is equal to $\frac{x_1^3}{x_5}$ for each observation. In other words, for each instance, you will cube the $x_1$ column and then divide by the $x_5$ column. 2. Drops the entire $x_4$ feature column if the passed function argument `drop_x4` is `True` and doesn't drop the column if `drop_x4` is `False`. (See further instructions below.) You must name your custom transformer class `Assignment4Transformer`. Your class should include an input parameter called `drop_x4` with a default value of `True` that deletes the $x_4$ feature column when its value is `True`, but preserves the $x_4$ feature column when you pass a value of `False`. This transformer will be used in a pipeline. In that pipeline, an imputer will be run *before* this transformer.
