A Sudoku puzzle uses a 9 × 9 grid in which each column and row, as well as each of the nine 3 x 3 subgrids, must contain all of the digits 1. . . 9. Figure 4.19 presents an example of a valid Sudoku puzzle. This project consists of designing a multithreaded application that determines whether the solution to a Sudoku puzzle is valid. There are several different ways of multithreading this application. One suggested strategy is to create threads that check the following criteria: • A thread to check that each column contains the digits 1 through 9 • A thread to check that each row contains the digits 1 through 9 • Nine threads to check that each of the 3 x 3 subgrids contains the digits 1 through 9 This would result in a total of eleven separate threads for validating a Sudoku puzzle. However, you are welcome to create even more threads for this project.

An 8-puzzle game consists of 8 sliding tiles, numbered by digits from 1 to 8 and arranged in a 3x3 array of nine cells. A configuration in the puzzle refers to some specific arrangement of the tiles in the array, where each digit is arranged into a different cell. One of the cell is empty (represented by a "*") and any adjacent tile can be moved into the empty cell. An example below c | 1 | 2 | 3 b | 4 | * | 5 a | 6 | 7 | 8------------------ Y/X a b c We use a 3-tuple (number, X, Y) to represent the position of a digit, where number is the actual digit, and (X,Y) is the coordinate value of the digit in the current configuration (e.g., in the configuration above, we have (5,c,b), meaning the digit 5 is at the position of (c,b)).Hence the configuration in the example can be represented as:[(1,a,c), (2,b,c), (3,c,c), (4,a,b), (5,c,b), (6,a,a), (7,b,a), (8,c,a)].Any move of an adjacent tile into the empty cell moves the current configuration into the one adjacent to it.…
✓ Exercises Exercise: Write a method _ and _ that computes the region representing the intersection of two regions. Exercise: Write a method _contains__, which checks whether a n-dimensional point belongs to the region. Remember, a point belongs to the region if it belongs to one of the rectangles in the region. ✓ Membership of a point in a region #@title Membership of a point in a region def region_contains (self, p): ### YOUR SOLUTION HERE Region._contains = region_contains [ ] # Tests 10 points. assert (2, 1) in Region (Rectangle((0, 2), (0, 3)), Rectangle((4, 6), (5,8))) assert (2, 1) not in Region (Rectangle((0, 1), (0, 3)), Rectangle((4, 6), (5, 8))) Exercise: Write a method _le_ for regions such that R <= S if the region R is contained in the region S. You can test this by checking that the difference between R and S is empty.

Computer Science I need the code for this in Alice programming Faery Magic Create a world that has at least 5 different objects from the Furniture Gallery and one Faery from the Fantasy/Faeries Gallery. The Faery has the power to make an object disappear. Everything that the faery touches disappear from the scene. Create an interactive game where the user can click one object at a time from the scene; then, the faery faces that object and moves toward it. Write a recursive method named CheckDistance, that checks whether the faery is very close to the object clicked by the user. If it is, the faery bends over to touch the object. After the faery touches the object, the object disappears (this is the base case of the recursion). If the faery is not yet close enough to the object to be able to touch it, the faery moves a small distance forward and the CheckDistance method is recursively called (this is the recursive case of the recursion). Include instructions for the game that appears…
Computer Science A Java swing program that lets the user draw a line that can be individually deleted or moved. make a JPanel to allow users to draw a line with their mouse, move the line to wherever, and delete each individual line chosen by the user. Use JRadioButton and/or JComboBox in a separate JPanel to allow users to choose to draw, move, or delete a line. The user should be able to have multiple lines at once Whenever necessary, the user should be prompted with instructions on how to continue or what is wrong. (For example; conformation prompt for deleting a line, or which line the user wants to delete)

Blackout Math is a math puzzle in which you are given an incorrect arithmetic equation. The goal of the puzzle is to remove two of the digits and/or operators in the equation so that the resulting equation is correct. For example, given the equation 6 - 5 = 15 ^ 4/2we can remove the digit 5 and the / operator from the right-hand side in order to obtain the correct equality 6 - 5 = 1 ^ 42. Both sides of the equation now equal to 1. Observe how removing an operator between two numbers (4 and 2) causes the digits of the numbers to be concatenated (42). Here is a more complicated example: 288 / 24 x 6 = 18 x 13 x 8 We can remove digits and operators from either side of the equals sign (either both from one side, or one on each side). In this case, we can remove the 2 from the number 24 on the left-hand side and the 1 from the number 13 on the right-hand side to obtain the correct equality 288 / 4 x 6 = 18 x 3 x 8 Both sides of the equation now equal to 432.

Moving Magic Square is the name of a game that is based on the concept of a magic square. A magic square is any square array of numbers, usually positive integers, in which the sums of the numbers in each row, each column, and both main diagonals are the same. For example, the 3 x 3 square in Table 1 is a magic square because the sum of every row, every column and the two diagonals is 15. Table 1 6 18 753 294 The game, Moving Magic Square, is played on any n x n grid containing positive integer numbers from 1, ..., n². The number n² is the movable number. You can move the number n² in one of four directions (up/down/left/right), and swap n² with the number that is currently occupying that cell. The player wants to move the number n² to reach a goal state such that the sum of the n numbers in every row, column, and both diagonals is equal to k. There are multiple states that satisfy this condition, and you can stop the game when you find the first goal state. In a 3 x 3 game, 9 is the…

A ? Jhinuk and her grandma have a special bond, they love playing puzzle games together. One day, grandma came up with a new game for Jhinuk to play. She found some old wooden blocks and put them together in a 3xN grid. Problem A A Game with Grandma To make the game more fun, grandma made up some imaginary rules: two players take turns picking a 2x2 section of the grid to color, with the rule that each cell can only be colored once. The player who can no longer pick a 2x2 section to color loses the game. The game sounded easy to Jhinuk, but there was a catch. Some of the blocks were cracked and couldn't be painted! Jhinuk and her grandma are both smart and play well, so they will never make a wrong move if there is a way to win. Can you write a code to figure out who will win given the starting state of the board? Grandma always lets Jhinuk go first 'cause she loves her so much. To help you write the code, she has provided you with some sample boards. 000 000 000 4 0000 0000 0000 5…
