Implementations of Dijkstra's shortest path algorithm in different languages. Head over to http://maxburstein.com/blog/introduction-to-graph-theory-finding-shortest-path/ to learn about implementing Dijkstra's algorithm. You can also learn about unit testing by visiting http://maxburstein.com/blog/introduction-to-unit-testing-in-python-and-ruby/.
Each example should feature this graph and should print the path A->B->F->H in some format.
ex. py dijkstras.py
>>> ['H', 'F', 'B']
C++, C#, Java, Javascript, Typescript, Coffeescript, PHP, Python, Ruby, Scala (Bolded languages have associated test-suites)
