TaskDeclare and implement 5 classes: FloatArray, SortedArray,FrontArray, PositiveArray & NegativeArray.1- The FloatArray class stores a dynamic array of floats and itssize. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the arrayelements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add tothe array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size.- An add method that adds a float at the front of…
Implement a CircularArray class that supports an array-like data structure whichcan be efficiently rotated. If possible, the class should use a generic type (also called a template), and should support iteration via the standard for (Obj o : circularArray) notation.
Implement a __setitem__ function that also supports negative indices. For example: W = L2(Node(10, Node(20, Node(30))))print W[ 10, 20, 30 ] W[1]=25print W[ 10, 25, 30 ] W[-1]=35print W[ 10, 25, 35 ] Complete the code: def L2(*args,**kwargs): class L2_class(L): def __getitem__(self, idx): <... YOUR CODE HERE ...> def __setitem__(self, idx, value): <... YOUR CODE HERE ...> return L2_class(*args,**kwargs) W = L2(Node(10, Node(20, Node(30))))print(W)W[1]=25print(W)W[-1]=35print(W)

Question 7 The method(s) with signature(s) defined in the Comparator interface is/are: Question 11 To simplify list processing, a header node is defined as a placeholder node at the beginning of a list and a trailer node is defined as a placeholder node at the end of the list. When a list is empty, which statement is NOT correct? Question 18 True or False? When an object of class ArrayCollection represents an empty collection, its numElements variable is 0. Question 20 True or False? If N represents the number of elements in the collection, then the add method of the SortedArrayCollection clas Question 21 True or False? Our LBList class inherits from the ABList class.
Please Use java only. Inthisassignment,youwillimplementaclasscalledCustomIntegerArrayList. Thisclass represents a fancy ArrayList that stores integers and supports additional operations not included in Java's built-in ArrayList methods. For example, the CustomIntegerArrayList class has a “splice” method which removes a specified number of elements from the CustomIntegerArrayList, starting at a given index. For a CustomIntegerArrayList that includes: 1, 2, 3, 4, and 5, calling splice(1, 2) will remove 2 items starting at index 1. This will remove 2 and 3 (the 2nd and 3rd items). The Cu stomIntegerArrayList class has 2 different (overloaded) constructors. (Remember, an overloaded constructor is a constructor that has the same name, but a different number, type, or sequence of parameters, as another constructor in the class.) Having 2 different constructors means you can create an instance of the CustomIntegerArrayList class in 2 different ways, depending on which constructor you…
Create a DeleteDuplicatesclass which consists of a deleteDuplicates method which takes the nums list as its parameter. Implement the deleteDuplicates method: Check if the input list is null or empty, and return an empty list if so. Initialize a pointer i to keep track of the unique elements. Use a for loop to Iterate through the list using another pointer j which starts at j=1 and goes until j=nums.size(); If the current element at j is not equal to the previous element at i using !nums.get(i).equals(nums.get(j), increment i and set the current element at j to the new position at i using nums.set(i, nums.get(j)). After the for loop ends, return the sublist from the beginning to i + 1, as this will contain all unique elements. Call the deleteDuplicates method with the sample list as argument: Call the deleteDuplicates method and pass the nums list as argument Store the result in a variable result Print the result to the console. Input: [1, 1, 2, 3, 3,…
There’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.
