kandi X-RAY | OrderedSet Summary

OrderedSet is a Swift library typically used in Server, Web Framework applications. OrderedSet has no bugs, it has no vulnerabilities and it has low support. However OrderedSet has a Non-SPDX License. You can download it from GitHub.

OrderedSet is essentially the Swift equivalent of Foundation's NSOrderedSet/NSMutableOrderedSet. It was created so Swift would have a unique, ordered collection with fast lookup performance that supported strong typing through Generics, and so we could store Swift structs and enums in it.

QUESTION

F# incomplete structured construct in my type

Asked 2021-Mar-23 at 13:48

I'm trying to implement a OrderedSet in F# (a set where you can get items by order of insertion). This is my first naive attempt at it (I still have to deal with possible duplicates in the IEnumerable passed to the constructor. The comparator is also still missing).

I don't think any of the above matters, though. I've been trying to solve the problem and, as far as I could gather from my research, it seems the issue is about indentation or lack of parentheses somewhere.

If I comment out my attempt at implement ISet, there is no issue, which leads me to believe there is something wrong with that part specifically. Here's the code:

Answered 2021-Mar-23 at 13:48

I only had to make two changes:

Indent the if under the do.
Remove this. in front of _set, because it's let-bound, not a class member.

You also have to finish implementing ISet, of course. Here's the resulting code:

After looking at the documentation it appears as though they moved away from a simple function in favour of the window function, theyre citing speed advantages as a reason for this.

https://wiki.postgresql.org/wiki/Aggregate_Mode

If you wanted to you could just create a function yourself but it seems as though the window function is the fastest way to get a NOT NULL result back from the db.

ANSWER

Answered 2020-Dec-25 at 12:30

I don't think such a structure exists. You didn't specify traversal performance requirements, so you could use a normal Set and add the values to a list and sort that list by score for traversal.

QUESTION

Does OrderedSet() still have a search parameter of O(1)?

Asked 2020-May-14 at 13:46

I have heard that when you perform an in operator on a list it has to search through O(n) objects while if you do it on a set it has to search through O(1) objects. To see what I mean go here. Does this still apply to OrderedSet?

...

ANSWER

Answered 2020-May-14 at 13:46

Which OrderedSet are you talking about? At this time (Python 3.8.3), there is not OrderedSet in the standard library.

Typically, OrderedSet implementations will implement __contains__ by delegating to the underlying set. So it will have the algorithmic complexity you would expect.

QUESTION

Python: sorted insert into list

Asked 2020-Jan-14 at 17:58

This is a common task when building a list incrementally: having sorted the container, subsequent inserts should inject values efficiently at the correct location such that the sorted container stays sorted, and an iterator readout onto a standard list is O(n), being perfectly clear: I am looking for a call to compiled O(logn) inserts into what amounts to a list, as I would expect in the ordered set I'd get from std::set (where I'd have to explicitly specify std::unordered_set to get the default python behavior).

OrderedSet (the missing python type) would accomplish this task. Is there a way to get this effect in python such that it is as efficient within the container as it would be expected to be in a general purpose compiled language?

Time Complexity of OrderedSet() in python

Asked 2019-Dec-19 at 22:40

I was going through this answer on Stack Overflow. I came to know about existence of OrderedSet in Python. I would like to know how it is implemented internally. Is it similar to hash table implementation of sets?

Also, what is the time complexity of some of the common operations like insert, delete, find, etc.?

...

ANSWER

Answered 2019-Dec-19 at 22:40

From the documentation available here

Implementation based on a doubly linked link and an internal dictionary. This design gives OrderedSet the same big-Oh running times as regular sets including O(1) adds, removes, and lookups as well as O(n) iteration.

There is also a discussion on the topic, see Does Python have an ordered set?
