What programming languages are available in walkccc.me's LeetCode Solutions?

Updated

walkccc.me's LeetCode Solutions are written in C++23, Java, Python, MySQL, and TypeScript. The site describes the collection as aiming to provide code with good readability and consistent style across various topics, while embracing new standards. If you want a solution in one of those five languages, it is likely covered; if you need a language outside that set, this is not the right resource.

Languages at a glance

Language Notes from the site
C++23 Listed first; the "23" signals a recent standard rather than older C++
Java Standard Java solutions
Python Python solutions
MySQL For database-oriented problems, where the answer is a query rather than an algorithm
TypeScript TypeScript solutions

What this means in practice

  • Five languages, one consistent style. The stated goal is readability and consistency across topics, so the same problem should look structurally similar whichever language you open.
  • Modern standards are intentional. C++23 being named explicitly suggests the code is not written against legacy C++ conventions.
  • MySQL is a different category. It appears because some problems are SQL problems; you would use it for those, not as a general-purpose alternative to the other four.
  • Coverage is topic-based. Solutions are organized across various topics rather than as one flat list, so you can navigate by problem area.

How to choose a language here

  • Pick the language you are actually practicing in, so the solution reinforces syntax you will use.
  • If you are comparing approaches, reading the same problem in two languages can clarify what is language-specific versus algorithmic.
  • If your target language is not among the five, you will need another source.

The same site also hosts CLRS Solutions, described as a crowdsourced work contributed by people around the world. That is a separate collection from the LeetCode Solutions and is aimed at the CLRS algorithms textbook rather than LeetCode problems.
