There are three main operations on rectangles: intersection, union, and difference. Among them, only intersection is guaranteed to return
another rectangle. In general, the union of two rectangles is... two rectangles, and the difference between two rectangles is ... a whole lot of
rectangles, as we will see.
We let you implement rectangle intersection. Of course, the intersection is defined only if the rectangles have the same number of dimensions.
The intersection is computed by taking the intersection of the intervals of the two rectangles for corresponding dimensions. If one of the
intervals is empty, you should return None.
[] # @ title Rectangle intersection
def rectangle_and(self, other):
if self.ndims != other.ndims:
raise TypeError("The rectangles have different dimensions: {} and {}".format(
))

I want answer for exercise 2 only...., and from exercise 1 you can get some information.
A boatman, a wolf, a sheep, and a cabbage are on the bank of a river. They have
a small boat that is capable of carrying the boatman and at most one other
animal/item with him. However, if left alone by the boatman, the wolf can eat the
sheep, and the sheep can eat the cabbage. How can all four be moved safely to
the opposite bank of the river?
Here is a nice visualization of the whole process in the original game. Disclaimer:
writers, testers and CodeChef are not related to this link.
This leads to a more general problem. If there are other groups of animals/items
with the boatman, is it possible to move them all to the opposite bank of the river in
such a way that nobody/nothing gets eaten?
We will give you the number of animals/items (not including the boatman).
Moreover, we will give you all a list of pairs of the form "X Y" where the X-th
animalitem will be eaten by the Y-th one if they are both on the opposite bank to
the boatman.
You are to determine whether it is possible to…

- Your task is to develop a Tic-Tac-Toe (also called as “Noughts and Crosses”) game in Java using Swing. In this assignment, you are asked to implement a single-player version of the Tic-Tac-Toe game with easy-to-use graphical user interface (GUI). One player will be the user and the second player will be artificial intelligence (AI), namely, the computer. The entire procedure of the implementation has been split into three tasks with detailed description and explanation provided. By completing the three tasks, you will develop your own Tic-Tac-Toe game. Task 1: GUI ImplementationPlease implement a GUI satisfying the following requirements.• A menu bar with two buttons “Reset” and “Quit”. User can click the “Reset” button to restore the software to the initial status. User can software the game by clicking the “Quit” button;• The top pane is an information board to display username and present some basic guidance to the user about this game. The information board will also print out the…arrow_forwardCreate a TestCard project with a TestCard class and a Card class. Data members for the Card class should be two numeric values representing the suit of the Card and the card's number. The Card class also has a constructor and methods for setting and getting the card information. See UML model. In the TestCard class within main(), deal two cards at a time by constructing two card objects. One card is the user's. The other is the computer's. Show both cards. Add a point to whoever had the higher card. Show who won the trick and the score. Scores don't change if a tie. Keep dealing until user wants to quit or 26 pairs have been dealt. UML for Card class -suit: int the number that corresponds to the suit of the card. 0 Hearts, 1 Diamonds, 2 Clubs, 3 Spades -value: int the value of the card.

The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation.

It means that the program should ask a person for body temperature in Celsius, and grant or reject access to a coffee shop. When a customer orders a coffee, they have to choose a size such as Small, Medium, and Large then, depending on the order, the price has to change. The price also has to change depending on the type of coffee. For example, for coffees that are similar to espresso, you also need to take every shot of espresso into account. The actual prices of the coffees depend on your imagination however, they should be realistic. Some hints: • Focus on dividing your program into multiple functions. • You can also return double or integer types of values from your functions, so use them if you can. • Don't just code a function every possible type of, and try to make it generic as much as possible. • Be creative.

Create accessors for all three variables. Write a toString() that will print/label the three sides. write some main code to create three instances of your class, one to test each of your constructors. you can input values or use fixed values. Display each instance using an implicit toString() call.arrow_forward
- 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…arrow_forwardImplement the Solver class.
