answer this code in scala . there are two qyestion in the pictures below and both are connected Lecture QuestionIn a package named "lecture11“, implement the following to expand the Flashlight/BoomBox functionality from the previous lecture question. Full functionality from theprevious lecture question is required.• Classes Battery, Electronic, BoomBox, and Flashlight as defined in the previous lecturequestion.• An object named UseElectronics with• a method named "useAll" that takes a List of Electronics as a parameter and returns Unit.Calls the "use" method on all the Electronics in the input list.[Notice that the specific method that is called depends on whether the Electronic is a BoomEor a Flashlight].A method named "swapBatteries" that takes two Electronics as parameters and returnsUnit.Exchanges the batteries between the two Electronics.Testing: In a package named "tests" create a Scala class named "TestElectronics" as a tessuite that tests all the functionality listed above. In a package named "lecture10“, implement the following.Lecture Question• class Battery withA constructor that takes a variable named "charge" of type Int.• abstract class Electronic withA constructor that takes no parameters.A state variable named "battery" of type Battery.• A method named "use" that takes no parameters and returns Unit (this can be abstract).• A method named "replaceBattery" that takes a Battery as a parameter and returns a Battery.This method swaps the input Battery with the Battery currently stored in this Electronic's state variable.The returned Battery is the one that was in the state variable when the method is called.class Flashlight that extends Electronic.A constructor that takes no parametersWhen a new Flashlight is created, assign the inherited state variable named "battery" to a new Battery with 5 charge (ie.Batteries included).• Override the "use" method to reduce the charge of the battery in the state variable by 1 if its charge is 1 or greater.class BoomBox that extends Electronic.A constructor that takes a variable of type Battery and assigns it to the inherited state variable named "battery“.Your BoomBox constructor parameter should have a different name than the state variable.Override the "use" method to reduce the charge of the battery in the state variable by 3 if its charge is 3 or greater.

Lecture Question In a package named "lecture11“, implement the following to expand the Flashlight/ BoomBox functionality from the previous lecture question. Full functionality from the previous lecture question is required. Classes Battery, Electronic, BoomBox, and Flashlight as defined in the previous lecture question. An object named UseElectronics with • a method named "useAll" that takes a List of Electronics as a parameter and returns Unit • Calls the "use" method on all the Electronics in the input list. [Notice that the specific method that is called depends on whether the Electronic is a Booml or a Flashlight]. • A method named "swapBatteries" that takes two Electronics as parameters and returns Unit. Exchanges the batteries between the two Electronics. Testing: In a package named "tests" create a Scala class named "TestElectronics" as a tes suite that tests all the functionality listed above. %3D

I am what you call a perfectionist. I always strive for perfection, and I appreciate everyone and everything that is perfect. That is why I have recently acquired an appreciation for perfect numbers! I absolutely need to know which numbers from 1 to 1000 are considered perfect. From what I recall, a perfect number is a positive integer that is equal to the sum of all its divisors other than itself. Example: 6 is a perfect number because the divisors of 6 other than itself are 1, 2, and 3, and 1 + 2 + 3 = 6. c++ code
Computer Science C++ please, use Monte Carlo integration to calculate the volume of a d-dimensional hypersphere of radius r = 1. (Note that for d=1, 2, and 3, the common names for d-dimensional volume are length, area, and volume, respectively.) Print out each volume and narrow the answer down to 4 digits with 99% confidence. How far can you push d for this method?
