Negative weights using Dijkstra's Algorithm
...so that a vertex cannot be enqueued more than once (e.g., using a marked[] array to mark those vertices that have been relaxed), then the algorithm is guaranteed to run in E log V time but it may yield incorrect results when there are edges with negative weights.

What kinds of patterns could I enforce on the code to make it easier to translate to another program
.... For example, Python has lists and dictionaries, while PHP only has assoc arrays.
The "learner" approach is to build something that works OK for a restricted subset of the language (such as only print statements, simple math, and variable assignment), and then progressively remove limitations. Tha...
