How to build source code

All the source code in this project is built with Bazel build system. Learn more about Bazel...

Why Bazel?

Bazel provides a unified way of building projects with multiple programming languages. Bazel's glanularity allows to have many build targets where each contains only source code related to the specific algorithm or data structure.

Install on macOS

brew install bazelisk

Install on Windows, Linux and macOS

npm install -g @bazel/bazelisk

Learn more about other installation options.

Run algorithms

In order to run desired algorithm use the following command:

bazelisk run @kotlіn//sequential/graph/dijkstra:dijkstra

Where @kotlin can be replaced with any of the available languages.
