Bracket Inc. wants to ship out new products using their excess brackets. They have tasked you with generating every possible assortment of brackets for some n brackets where the brackets will match

• A bracket match is an opening and closing version of the same kind of bracket beside each other ()
• If a bracket matches then outer brackets can also match (())
• n will be an even number
• The valid brackets are ()[]{}

For example for n = 4 the options are

• ()()
• (())
• [][]
• [[]]
• {}{}
• {{}}
• []()
• ()[]
• (){}
• {}()
• []{}
• {}[]
• ({})
• {()}
• ([])
• [()]
• {[]}
• [{}]

You must accept n as a command line argument (entered when your app is ran) and print out all of the matches, one per line

(It will be called like node main.js 4 or however else to run apps in your language)

You can use the solution tester in this post to test you followed the correct format https://programming.dev/post/1805174

Any programming language may be used. 2 points will be given if you pass all the test cases with 1 bonus point going to whoevers performs the quickest and 1 for whoever can get the least amount of characters

To submit put the code and the language you used below

Hey everyone! I'll be going through and making features for the site soon (as I've almost got my laptop back) and wanted to know if there was any features that are wanted that I dont already have noted down

I'm currently planning to do:

• Customizable icon shapes (circle, hexagon, etc.)
• Flairs
• Ability to block an instance
• Ability for admins or community mods to hide communities from the all feed
• Community short descriptions (to show in the community list + top of sidebar)

And polls are also being worked on by snowe

Will try to get the changes merged into lemmy itself as well but they'll be released here first

IO.puts "Hello, world!"

Welcome to the first programming challenge! Three of these will be posted a week and you can complete it in any language you want.

You get a point for completing an easy challenge, 2 for a medium, and 3 for a hard. For each challenge if you solve it in the least amount of characters you get a bonus point, and if your code runs the fastest when I check it you also get a bonus point. (ties mean everyone who tied gets the bonus point although exact duplicate answers wont count)

Ill be posting a leaderboard that will show the people who have the most points every month

Submissions will be open for a week

As a new hire of bracket inc., you have been tasked with getting rid of excess brackets lying around the facility. You must simplify a series of brackets so that only brackets that dont have a match remain (a match is an opening and closing bracket of the same type beside each other). The final result should have no matches

As an example for the input [(({})({)(()}] the expected output would be [(({)(}]

These are the valid types of brackets: (){}[]

Your system will be tested against 10 different unknown test cases before it is unleashed on the facility. In order to complete this task you must pass all of the test cases.

Any programming language may be used and to submit an answer reply on this post with the code and the language you coded it in

Edit: Clarification, you must take input in from the user using the program instead of them being hardcoded. (makes it easier to test)

I've been experimenting with putting random quotes from the !quotes@programming.dev community as taglines in the instance.

It will automatically put a random quote every time you go to a page in the site. I put the ones that are shorter so they don't flood the page, and that were upvoted.

Theres also a link back to the quotes community if you click on the credit where you can discuss about that quote. As more quotes get added to the community the pool of tagine quotes will grow

• note they may not be visible on certain lemmy clients depending on what features the clients support but they work on web

This is a community that will have various programming challenges to complete (in any language of your choosing)

Posts will be done three times a week (one easy, one medium, one hard) with the first easy one coming tomorrow

I'm currently running the community until somebody else volunteers but if anyone else wants to manage it let me know
