DataStructures | C # data structures missing from core libraries

For an assignment i had different DataStructures (in C#) that I needed to implement. That part was easy. But I am also required to make a main menu driven programme for all those projects. So i searched a bit and found out a way. For example i had a project named linkedlist with namespace as Implementing_LinkedList and another project queue and namespace as Implementing_queue. To make a menu driven programme i just created another project named Assignment with namespace assignment. Mainconsole. Then i changed the namespace of linkedlist project to Assignment.Implementing_LinkedList and similarly with queue.Also made all the methods and classes public. Then i just called the main method of linkedlist inside main method of assignment as follows

Implementing_LinkedList.Program.Main();

Main method is inside a class named program in linked list project and it worked. Now i want to know how this worked because specifically .MainConsole part and if there is any other way to acheive this.

(Also i am pretty new to Stack overflow so pardon me for the extra long question but i didn't want to skip any details)

Trying to learn datastructures, I made this class for a stack. It works just fine with integers but it throws a mysterious error with strings. The class List is the API for my stack. Its meant to resize automatically when it reaches the limit. The whole code is just for the sake of learning but the error I get doesn't make any sense and it happens somewhere in some assembly code.

Hello all i need a little help in finding solution for a datastructure problem using python . I have two datastructures, batches dictionary which contain batch qty for a certain batch and second datastucture so_data is list of orders. Now task is to loop over so_data and consume batchwise quantities in batches on FIFO basis.

I have wsdl with ArrayOfVEHICLE type:

I'm trying to implement a server in Rust and I wonder if I'm missing something to make it less complex. The simplification of my project would be that I want to have different clients connected to a server, each receiving what the others publish in real time.

I want to do this in an async runtime (tokio atm). Each client has its stream, which I divide into a stream and a sink:

I have snippet of inputs that I render to the html page when a condition is met, everythings works appropriately except for the input with type file, I want to upload the files when a change has occured but the file object is not in request.FILES, it's in request.POST now I don't mind it being request.POST but the files is displayed as 'multiple': ['[object File]']

I have a dictionary in Julia that I want to sort by values. I found a couple of ways to do it. For instance

I am trying to move from R to Julia.

So I have a dataset with 2 columns of prices and 2 conditional columns telling me if the price is "cheap" or "expensive".

So I want to count how many "cheap" or "expensive" entries are.

So using the package DataStructures I got this:

I’m new to ViewSets and am trying to get the values sent from the front-end fetch method to Django’s request object in the create function. I don’t know whether it’s just a simple syntax error or whether the data isn’t being sent properly from the front-end, but I think it’s a back-end issue.

The stringified data in the post method seems to log correctly at the front-end like with this test:
