I have an interface, an abstract class, and three different classes, which can be morphed into other class of the same level. The problem is, how to implement this kind of structure without violating the SOLID principles, or what’s the best way to transform a class into another similar class, but with some restrictions? TheRead more
Task: Design a vending machine which does the following: Accepts coins of 1, 5, 10, 25, 50 cents or notes of 1 and 2 User selections: Candy, snacks, nuts, Coke, Pepsi and soda Allow user by cancelling the request, returns the product and change, Note : i understand the need of using std::cin/std::cout etc,. JustRead more
I am looking to find the best implementation that would basically be a singleton strategy delegate design pattern. What would be the best/cleanest way to create singleton functionals in Java? I want to prevent unnecessary instance creation. I also want to make it so I can look up the correct function without doing a switchRead more
I am looking for a way to define anticummuting numbers (variables) in mathematica. Let say we have a set of four variables like $ {x_1,x_2,x_3,x_4}$ which I need to get all possible permutation of them then multiply to appear as a sum as $ $ x_1*x_2*x_3*x_4+x_1*x_2*x_4*x_3+(22\,{\rm terms})$ $ but here as we said these variablesRead more
I am fairly new to python 3. Is there a way to implement a +/- function into a single line of code? In this simple quadratic formula solver function I wrote, I used two separate variables and returned them both. Is there a cleaner way to do this? def Quadratic_Solver(a,b,c): “”” This function returns solutionRead more
Good morning, @Sven and GSA pplz… I don’t know that you would want or need to do this. Of course, I expect you to be better able to gauge what is actually worth your time and worth the users’ time. So this is just an idea, not really a request. Right now, I can stopRead more
While Mathematica has tons of built in functionality, it can be fun / useful to implement things from scratch to ensure understanding. In this case I am trying to implement Smart Local Moving. The paper uses the Karate Club network, so lets load it: G = ExampleData[{“NetworkGraph”, “ZacharysKarateClub”}] but prefers to use the Adjacency MatrixRead more
I am not sure if this is the right place to ask this question, but I believe there will be people here who do computations on computer algebra packages like Sage in their work. I have been using Sage to perform some matrix rank computations. It turns up a few bizarre results occasionally. For example,Read more
Scenario. ViewModel has a property State. View has a ComboBox that allows to change value of State. ViewModel needs to run some validation (call bool ValidateState(State value) method) before setting value of State property. Question. How would you implement it? My concerns. I want my solution to be generic so I could use it inRead more
