Python:
Take your searching and sorting functions and put them into a class.
The constructor should take a list as a parameter use the classes sort method and store the sorted list in a class property.
A "search" method should return true or false if the item is found.
A "count" method should return 0 or the number of times the item is found.
For fun, you can create a method to generate a list of random numbers (and then sort it).
1)
Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print (X)).
Car Prices are as follows according to the segments.
0-19999 -> Z20000-29999 -> Y30000-44999 -> T45000-100000 -> P
Apply the Car list using "Single Linked List"(Node, newNode, head).
The program should be written in JAVA.
Below is the specs and my main method. (ignore add and remove method for now)

Part 1 - Tweet Bot
To start analyzing tweets, we first need to read in and manage the state of tweets. To do this, create a class called TweetBot. A TweetBot should have the following constructor and methods:
Constructor
public TweetBot(List<String> tweets)
Given a List of tweets, initialize a tweet list containing all tweets from the given collection. Note that you should not initialize your tweet list to the given List reference. You should create a new data structure and copy over all of the tweets from the given List, leaving the given List unmodified after the constructor is finished executing.
Throws an IllegalArgumentException if the size of the given collection is less than 1.
You may assume the given collection contains only non-empty and distinct strings.
Methods
public int numTweets()
Returns the number of tweets currently in the tweet list.
public void addTweet(String tweet)
Adds the…

Tasks have a priority between 1 and 9, and a description (which you can come up with on your own, say, “wash dishes”). The program is going to prompt the user to enter the tasks by running the method add_priority_description, the program adds a new task and prints the current list with priority 1 tasks on the top, and priority 9 tasks at the bottom. The program will continue to ask the user if they want to add another tasks, and repeat the add_priority_description method, or enters Q to run the quit method to quit the program. Sample output (not limited to) 1. Study for the final 1. Take the final 2. Watch Justice League with friends 3. Play ball 9. Wash Dishes 9. Clean room. There is a possibility of two tasks having the same priority. If so, the last task that was entered gets to be printed first. Use HEAP in your solution. (Java)arrow_forward
- The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…arrow_forwardWrite a method called addSmallest to be considered in a class outside the KWArrayList class.

The list is named dogFoodList. (This means dogFoodList points to the first node in the list.) A node in the list contains the name of the dog food (a String), a dog food ID (also a String) and the price (a double.) a.) Create a class for a node in the list. b.)

- in c++ codearrow_forwardCan you help me please: Write a program to test various operations of the class doublyLinkedList. Your program should accept a list of integers from a user and use the doubleLinkedList class to output the following: The list in ascending order. The list in descending order. The list after deleting a number. A message indicating if a number is contained in the list. Output of the list after using the copy constructor. Output of the list after using the assignment operator. An example of the program is shown below: Enter a list of positive integers ending with -999: 83 121 98 23 57 33 -999 List in ascending order: 23 33 57 83 98 121 List in descending order: 121 98 83 57 33 23 Enter item to be deleted: 57 List after deleting 57 : 23 33 83 98 121 Enter item to be searched: 23 23 found in the list. ********Testing copy constructor*********** intList: 23 33 83 98 121 ********Testing assignment operator*********** temp: 23 33 83 98 121 Your program should use the value -999 to denote the…arrow_forwardCreate the Median class that has the method calculateMedian that calculates the median of the integers passed to the method.

There are two numbers in the "middle", the median is the average of these two numbers. Method Call Return Value m.calculateMedian(3, 5, 1, 4, 2) 3.0 m.calculateMedian(8, 6, 4, 2) 5.0 m.calculateMedian(9, 3, 7) 7.0 m.calculateMedian(5, 2) 3.5 Hint Finding the median requires that the numbers be in order.

Write the definition of a function that returns the data of the kth element of the linked list. If such element is not exist in the list, exit the program. b.

Revise the genericStack class we did in the class to implement it using an array instead of ArrayList. You need to check the array size before adding a new element. If it is full, create a new array that double the current size and copy the elements from the current to the new array and then add the new array. (2 points) 3.
