degree_sequence

degree_sequence(k: PlanarDiagram) → tuple

Compute and return the degree sequence of all nodes in a given PlanarDiagram.

Args:

k (PlanarDiagram): The input planar diagram, where each node has a certain degree

representing the number of endpoints connected to it.

Returns:

tuple: A tuple containing the sorted degree sequence (in ascending order) of nodes in the

planar diagram.
