Suppose that there will never be more than one character of pushback. Modifygetch and ungetch accordingly.

Implement the Solver class. In doing so, you are allowed to define other classes to help you (as well as use “built-in” Java classes or the book’s classes). The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of booleans and returns a char array containing a minimal sequence of moves that will lead to the solved board (all the cells around the edges being filled). The board configuration is passed in as a 5-by-5 boolean array of Booleans with exactly 16 true cells (filled) and 9 false cells (empty). The solve method then returns an array of characters representing a minimal sequence of moves that solves the puzzle. In other words, if the characters from the returned array are used in order as input to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions…

4. Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print them to the console. What would the code look like for this? 5. Write a method signature for a method called foo that takes an array as an argument. The return type is void. 6. What is the difference between remove and clear in ArrayLists.

In Checkpoint A, the game will not yet be playable as a two-player game. It will be playable by you in a type of "solitaire mode." Implement these functions from the template following the description (specification) in their docstring: show_top_card() get_top_card() add_card_to_discard() check_racko() find_and_replace() play_hand() The main function to drive the game has been provided. Missing input/output statements are part of play_hand() and left for you to implement, guided by the sample input/output. None of the other functions left to implement use input or print. The case / capitalization of user input should be ignored. On any invalid user input, the program should exit with a non-zero exit code. Hint: Use Python Tutor. as much as possible when testing gameplay. Zybooks requires you specify all your inputs in advance and it is less enjoyable to play that way. Sample input/output 1 When the inputs are: no yes 1 yes 5 yes 7 The expected behavior is (inputs are shown in-line)…

Movie Recommendations via Item-Item Collaborative Filtering. You are providedwith real-data (Movie-Lens dataset) of user ratings for different movies. There is a readmefile that describes the data format. In this project, you will implement the item-item collab-orative filtering algorithm that we discussed in the class. The high-level steps are as follows: a) Construct the profile of each item (i.e., movie). At the minimum, you should use theratings given by each user for a given item (i.e., movie). Optionally, you can use other in-formation (e.g., genre information for each movie and tag information given by user for eachmovie) creatively. If you use this additional information, you should explain your method-ology in the submitted report. b) Compute similarity score for all item-item (i.e., movie-movie) pairs. You will employ thecentered cosine similarity metric that we discussed in class. c) Compute the neighborhood set Nfor each item (i.e. movie). You will select the moviesthat…

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…

Modify the GeometricObject classto implement the Comparable interface and define a static max method in theGeometricObject class for finding the larger of two GeometricObject objects.Draw the UML diagram and implement the new GeometricObject class. Writea test program that uses the max method to find the larger of two circles, the largerof two rectangles.

Hi, would you be able to assist me with problem in java code. ......Four new students have arrived at Hogwarts School of Witchcraft and Wizardry. The students will join one of the four houses, Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. The sorting hat has gone missing so in the meantime students will provide a list of the houses they wish to join and the Houses will rank the students in the order they wish to choose. You have been tasked with creating a program to determine a stable match between the students and Houses. The students will get to select their house of choice one at a time. If a student selects a house that is already chosen but rates higher on the list for that house, they are paired to that house and the student who is now un paired will need to select a new house form their ranked list.   The program will need each student's name and list of house preferences. Additionally, it will need each house’s name and ranked list of students. How you implement that…
