Leetcode Solutions in Scala
This project was created with a few purposes
First it is to promote language Scala and its functional approach to solve problems, Scala is expressive, succinct meanwhile far too much underrated. Second let's just admit one cannot judge the engineering calibers of another in one hour technical interview, I personally have had and failed a few and I want to do something to alleviate this madness of the industry. Use Search above and type in some method names to get the point ...
The listed solutions are by no means complete or optimal, if you would agree the causes, and feel like to contribute solutions, fixes or scaladocs to better illustrate everything, all PRs are welcome !
To maintain its goal please take a few notes too,
- Respect Scala CoC.
- Solutions shall pass all of their tests in leetcode, using plain Scala and its std library only.
- Solutions need to bundle their own unit tests, this project uses uTest.
- Always prefer functional programming, which requires immutable data, pure functions etc, and keep it to the point.
- Always prefer a generic solution, which captures the gist of a pattern or an algorithm, even if it implies some tradeoffs and becomes slightly suboptimal in terms of computational or space efficiency.
- Try to achieve performance only after doing it right, iterate above notes for clarification, although this might defeat the original leetcode intention, one might be surprised that functional programming can be performant too.
- Extra boilerplates are needed in package object so that Scaladoc can better serve us.
- Last not the least, use Scalafmt
