- can you please help me with this problem:you will develop an AI for a game in which two players take turns placing 1 x 2 dominoes on a rectangular grid. One player must always place his dominoes vertically, and the other must always place his dominoes horizontally. The last player who successfully places a domino on the board wins. n infrastructure that is compatible with the provided GUI has been suggested. However, only the search method will be tested, so you are free to choose a different approach if you find it more convenient to do so. The representation used for this puzzle is a two-dimensional list of Boolean values, where True corresponds to a filled square and False corresponds to an empty square. tasks:In the DominoesGame class, write an initialization method __init__(self, board) that stores an input board of the form described above for future use. You additionally may wish to store the dimensions of the board as separate internal variables, though this is not required.…arrow_forwardDon Norman suggests organizing screens and menus functionally, designing commands and menu choices to be distinctive, and making it difficult for users to take irreversible actions. Norman also says to provide feedback about the state of the interface (e.g., changing the cursor to show whether a map interface is in zoom-in or select mode) and designing for consistency of actions (e.g., ensuring that Yes/No buttons are always displayed in the same order). State one example you have seen where you know these rules have been violated. Although this is crucial to a user interfaces success, suggest why there may be challenges to implement some of Norman’s guidelines.arrow_forward1.

How to make Java OpenGL coding from answer No.1, so that the additional 3D shape rotates on its axis (just like the earth’s rotation, but we may choose which axis to rotate on, x, y, or z-axis) ? answer with coding (plug & play)arrow_forwardDesign and implement a class called RandomArray, which has an integer array. The constructor receives the size of the array to be allocated, then populates the array with random numbers from the range 0 through the size of the array. Methods are required that return the minimum value, maximum value, average value, and a String representation of the array values. Document your design with a UML Class diagram. Create a separate driver class that prompts the user for the sample size, then instantiates a RandomArray object of that size and outputs its contents and the minimum, maximum, and average values.arrow_forward
