- :Write some statements that display a list of integers from 10 to 20 inclusive ,each with its square root next to it. Write a single statement to find and display the sum of the successive even integers 2, 4, ..., 200. (Answer: 10 100) Ten students in a class write a test. The marks are out of 10. All the marks are entered in a MATLAB vector marks. Write a statement to find and display the average mark. Try it on the following marks: 580 10 3 85794 (Answer: 5.9)def winning_card(cards, trump=None): Playing cards are again represented as tuples of (rank,suit) as in the cardproblems.pylecture example program. In trick taking games such as whist or bridge, four players each play one card from their hand to the trick, committing to their play in clockwise order starting from the player who plays first into the trick. The winner of the trick is determined by the following rules:1. If one or more cards of the trump suit have been played to the trick, the trick is won by the highest ranking trump card, regardless of the other cards played.2. If no trump cards have been played to the trick, the trick is won by the highest card of the suit of the first card played to the trick. Cards of any other suits, regardless of their rank, are powerless to win that trick.3. Ace is the highest card in each suit.Note that the order in which the cards are played to the trick greatly affects the outcome of that trick, since the first card played in the trick…please code in python Forbidden concepts: recursion, custom classes Create a program for a used car dealership that buys and sells cars. The dealership currently has an S14, 240z, R33, and a 350z. The program must keep track of inventory. There must be options to add, remove, or print the list of cars, along with a killswitch.
- Instruction: 1) Do not change the name of class. 2) Should write each line comments to explain your code. 3) Follow the guidelines we discussed in our class in submitting programming assignment when you submit via Bb. 4) Use the attached file in Bb to work on this Lab. Extend the class (linkedListType and/or unorderedLinkedList) by adding the following operation: We discussed the function deleteSmallest() as find and delete the first occurred smallest element in a list. In this lab, we will implement the following function (see (A)) and write a test program to perform several tasks (see (B)). (A) Find the smallest element appeared in the list. Then, delete all occurrences of the item from the list. Add these as abstract functions in the class linkedListType and provide the definitions of these functions in the class un- orderedLinkedList. (Hint: add the abstract type ( virtual Type detectSmallestElement () 0:) in the class linkedList Type) %3D (B) Write a test program to perform the…Recursion Practice Welcome back! In this lab, we will be reviewing recursion by practicing with some basic recursion problems. Objectives Increase familiarity with recursive logic by working through several recursive problems. Taking into consideration a few corner cases through analyzing the test cases. Using a regex expression that will remove punctuation. Getting Started This lab includes the following .java file: L4/└── Recursion.java└── Main.java**Main.java is a read-only file used for testing. It is not included in the starter jar.Here is the starter jar if you would like to code in a different environment: L4.jar. Please complete ALL functions. Make sure to read the description for each function carefully. Do not include any for or while loops in your methods. These can all be completed in a purely recursive style, so do it recursively! In the spirit of incremental development, implement each method one at a time, look at the test cases and take into consideration what is…Evaluate the following Postfix expression to find the final value.

- Part III - Create Your Own Art Art.java In this part you will create a program Art.java that produces a recursive drawing of your own design. This part is meant to be fun, but here are some guidelines in case you're not so artistic. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. For full credit, Art.java must not be something that could be easily rewritten to use loops in place of recursion, and some aspects of the recursive…What's Hiding Amongst the Crowd? Language - Java Script A word is on the loose and now has tried to hide amongst a crowd of tall letters! Help write a function to detect what the word is, knowing the following rules: The wanted word is in lowercase. The crowd of letters is all in uppercase. Note that the word will be spread out amongst the random letters, but their letters remain in the same order. ● Examples detectWord("UcUNFYGaFYFYGtNUH") → "cat" detectWord("bEEFGBuFBRrHgUHINFYaYr") → "burglar" detectWord("YFem HUFBbezFBYZF BYLleGBYEFGBMENTment") → "embezzlement"Topical Information Use C++. This lab should provide you with practice in file handling, stream formatting, and some string manipulation. Classes might come in handy, too. Program Information Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. As an example, you might have the data file contain: # name # student number # address1 # address2 # phone number…
- Python only** define the following function: 1. This function must add a task to a checklist, setting its initial value to False. It will accept two parameters: the checklist object to add to, and the task name to add. In addition to adding the task, it must return the (now modified) checklist object that it was given. There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.Write a program in Java, Python and Lisp When the program first launches, there is a menu which allows the user to select one of the following five options: 1.) Add a guest 2.) Add a room 3.) Add a booking 4.) View bookings 5.) Quit The functionality of these options is as follows: 1.) When users add a guest they provide a name which is stored in some manner of array or list. Guests are assigned a unique ID value where the first guest added is assigned the ID value 1, the second guest added is assigned the ID value 2 and so on. 2.) When users add a room they provide a room number and a room capacity (i.e. how many people can stay in the room at any one time) which is stored in some manner of array or list. Rooms have a property which indicates if they are booked or not for any given date – please see the Room Booking Dates section below for some guidance on the easiest way to implement this. 3.) When users add a booking they provide a guest ID, room number, the number…Art.java In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin). Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. call…
