Personal archive for answered, unanswered, and failed leetcode and interview questions that I have attempted or want to attempt.
The best method to use this archive is with the archive section. Here you can find quick links to my solutions and to the problem itself. I have included the name of the Leetcode problem so you can easily find it with a search in your browser of choice.
If you hate documentation, you can also navigate to src/main/scala and find all of the solutions.
I have written test cases for (most of) the solutions, and these can be found under src/test/scala.
The majority of solutions have been resolved with Scala, managed and tested with sbt (which also handles Java solutions).
However, a few other languages can be found that cannot be handled by sbt; these will need to be run seperately, likely inside the Leetcode editor.
As the archive has been setup with sbt, you can use sbt commands.
Compile the code with sbt compile, test with sbt test, and sbt console will start a Scala 3 REPL.
Due to the nature of this project there are no main methods for running the code, and as such sbt run won't produce any meaningful results.
If you want to extend this project yourself, I recommend introducing and running more test cases.
