(PLEASE USE JAVA AND JFRAME GUI) Game rules:The game consists of a two-dimensional field of size m × n (game field). Each element ofthe game field is a button with a number assigned to it.Initialization of the game:• The numbers on the buttons of the game field are set to a random digit between 0and 9• The target value is displayed above the game field• The current sum of the numbers displayed on the buttons of the game field is printedbelow the game field• The number of moves to completion is displayed in the upper right corner above thegame field.Playing:The first move is determined by the player by selecting any button (button A) on thegame field.1. The player is allowed to choose a second button (button B) located in the columnor row of the previously selected button (A).2. Upon selecting the second button (B), the value of button (A) is updated accordingto the following formula: A = (AoperationB)mod10.3. The operation for the basic game will be +.4.

(Python matplotlib or seaborn) CPU Usage We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight. Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart: When does the worker typically take lunch? Did the worker do work on the weekend? On which weekday did the worker start working on their computer at the latest hour? cpu_usage = [ [2, 2, 4, 2, 4, 1, 1, 4, 4, 12, 22, 23, 45, 9, 33, 56, 23, 40, 21, 6, 6, 2, 2, 3], # Monday [1, 2, 3, 2, 3, 2, 3, 2, 7, 22, 45, 44, 33, 9, 23, 19, 33, 56, 12, 2, 3, 1, 2, 2], # Tuesday [2, 3, 1, 2, 4, 4, 2, 2, 1, 2, 5, 31, 54, 7, 6, 34, 68, 34, 49, 6, 6, 2, 2, 3], # Wednesday [1, 2, 3, 2, 4, 1, 2, 4, 1, 17, 24, 18, 41, 3, 44, 42, 12, 36, 41, 2, 2, 4, 2, 4], # Thursday [4, 1, 2, 2, 3, 2, 5, 1, 2, 12, 33, 27, 43, 8,…
