QUESTION
Overall the code is working except one part.
The code first outputs sorted string in alphabetical order. Then the repeated characters are removed so each letter is displayed just once. My problem here is when I input "datastructures" it displays acdersttu, but instead I should have acderstu, which means with only one t. Where is the problem?
My code:
ANSWER
Answered 2022-Feb-16 at 06:34The rule which you defined is applicable only when there are 2 repeated characters, since 3 t's are there it is not working fine. Below code is the change, for the second loop.
QUESTION
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)
...ANSWER
Answered 2022-Feb-16 at 14:20You don't have to rename namespaces or anything. Each program's Main() function is static and it can be called from any other function using a fully qualified name.
QUESTION
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.
...ANSWER
Answered 2022-Feb-09 at 21:47string* list = new string[max]; in the resize method defines a new variable named list that "shadows", replaces, the member variable list. The member list goes unchanged and the local variable list goes out of scope at the end of the function, losing all of the work.
To fix: Change
QUESTION
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.
...ANSWER
Answered 2022-Feb-06 at 16:34Finally resolved:
Well the task was to consume batchwise stock for Sales order list. So after looping sales order I checked:
If so_qty is less than batch qty and fit within given index of batch qty then decreased so_qty from batch qty, then appended current batch into consumed batch list of dictionary which is maintaining batchwise consumption for each order and finally set current so_qty to 0 as order is fullfilled
Else if so_qty is greater than batch qty than reduce batch qty from current so_qty, append remaining batch qty to consumed batch list, set current batch to 0 and continue with same so_qty unless it became 0 and break the loop for current so_qty when 0.

QUESTION
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:
...ANSWER
Answered 2022-Jan-19 at 14:22tokio::sync::broadcast seems to match your requirements pretty well.
If you want to implement it yourself, options for communication between threads include:
std::sync: atomics, synchronization objects, etc.tokio::sync: async-compatible versions of synchronization objects, various kinds of channels, etc.futures_core::stream/tokio_stream: likeIteratorbut async
QUESTION
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]']
My partial template
...ANSWER
Answered 2022-Jan-04 at 16:20Did you add/set hx-encoding to multipart/form-data?
According to the docs https://htmx.org/docs/#files
If you wish to upload files via an htmx request, you can set the hx-encoding attribute to multipart/form-data. This will use a FormData object to submit the request, which will properly include the file in the request.
QUESTION
I have a dictionary in Julia that I want to sort by values. I found a couple of ways to do it. For instance
...ANSWER
Answered 2022-Jan-04 at 15:45As by the docs, for OrderedDict
order refers to insertion order.
I don't know how this can "lose its order down the line", but maybe you are just mutating stuff?
Probably what you want is closer to a SortedDict; however, this sorts by keys, not values. A dictionary sorted by values is a bit of an unusual application.
If you want a mutable data structure with fast lookup by key and iteration sorted by value, you could emulate this by a two-level approach: a normal dict for storing a mapping between original keys and tokens, and a second SortedMultiDict{ValueType, Nothing} to emulate a sorted multiset into which the tokens index. Then you define your own mechanism for indirect lookup through tokens somehow like this:

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:

QUESTION
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:

Answered 2021-Dec-12 at 22:15You wrote the data as body of the request in a JSON format. You thus should decode the JSON format to a dictionary with:

Install DataStructures
You can use DataStructures like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the DataStructures component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
