Task: Sketch a blueprint of your dreamhouse
A blueprint of your dream house should include a map of the floor plan, including details such as the number and size of rooms, as well as the location of windows, doors, and stairs. It should also include a layout of the yard, including the placement of landscaping and outdoor features. Additionally, a blueprint should include specific details about the materials and finishes that will be used.
Implement clear board functionality
Instructions
The clear button can now be implemented.
The clear button should reset the game board to all values being false. The living cell count and generation count should also be set to zero.
The status text will need to be updated.
Finally, the drawing panel will need to be refreshed.

- The goal of Snake is to create a snake as long as possible. This is achieved by guiding the snake to an apple on the game board. The snake cannot stop moving, and dies whenever it hits something (excluding apples). Because the snake is growing longer and longer as the game progresses, it gets increasingly difficult to avoid collisions with the snake itself. The player can change the direction of the head of the snake by using the arrow keys. At step in the game, there is always an apple somewhere on the board. If the snake eats an apple, the snake becomes one cell longer. A new apple is placed on a random location, excluding all places covered by the snake. When the snake reaches a side of the game board, it re-emerges at the opposite end.arrow_forwardUsing java card Graphic GUI, create a card game with a card layout in which 13 cards are displayed and if that card has the king of heart, then lose if not the player winsarrow_forwardQ3:Draw an ellips have radius rx= 7 , ry = 8 ?

- A number maze is an n × n grid of positive integers. A token starts in the upper left corner; your goal is to move the token to the lower-right corner. On each turn, you are allowed to move the token up, down, left, or right; the distance you may move the token is determined by the number on its current square. For example, if the token is on a square labeled 3, then you may move the token three steps up, three steps down, three steps left, or three steps right. However, you are never allowed to move the token off the edge of the board. 6 3574 5 315 3 283 35 74 6 53 15 1 4 2 8 3 1 4 4 5 7 2 3 4 5 7 2 3 3 1 3 2★ 3 KT3 A 5 × 5 maze that can be solved in eight moves In this problem, you will design and analyze an efficient algorithm that either returns the minimum number of moves required to solve a given number maze, or correctly reports that the maze has no solution.

It needs to pass all of the simulations. Thanks in advance Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading. Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern. For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example: Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext…arrow_forwardcreating a roulette wheel. The pockets are numbered from 0 to 36. The colors of the pockets are as follows: Pocket 0 is green. For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. For pockets 29 through 36, the odd-numbered pockets are black and the even-numbered pockets are red. Create a class named RoulettePocket. The class's constructor should accept a pocket number. The class should have a method named getPocketColor that returns the pocket's color, as a string. Demonstrate the class in a program that asks the user to enter a pocket number, and displays whether the pocket is green, red, or black. The program should display an error message if the user enters a number that is outside the range of 0 through 36.arrow_forward
- What happens if you open a picture and then change the size of the frame? You might try opening a picture once you've adjusted the frame size to your liking.arrow_forwardThe game is played in the magic maze, as shown below. The squares are flaming lava pools. If you try to cross them you will die. The grid lines are passageways and are safe to travel in. You can start at any location on the grid but must travel in the passageways. You may travel as far as you want in any direction, but once you turn, you must repeat that distance and you may only make left turns. You may not reverse direction inside the tight passageways. You must end up at the same spot you started at. If you successful, then you gain a magic coin, which automatically appears. You can start over again and again in a different or same starting spot and earn new magic coins, but the routes you take must differ somehow for each magic coin. That is, no magic coins for the exact same route as previously done. If the route varies in any way (perhaps it is the same starting location and ending location as a previous route, but longer), it will earn a new magic coin.
