Grid graphs in this code can all be considered undirected but are not acyclical, therefore visited nodes are marked to avoid infinite recursion. In practice, directed 2D grid graphs are also possible ...

The code is fully typed and makes use of composition with Protocol classes so that valid directions, traversal strategies, and even 2D graph types can be readily exchanged with minimal refactoring.

To create a directed graph in Python for solving problems on LeetCode, you typically represent the graph using data structures such as adjacency lists.

Graph Data Modeling in Python will guide you through designing, implementing, and harnessing a variety of graph data models using the popular open source Python libraries NetworkX and igraph.

Python allows free creation of plots, unlike expensive, stagnant graphing calculators. Import NumPy and Matplotlib for basic linear and polynomial plots in Python. Seaborn lets you make ...
