number_of_link_components

number_of_link_components(k: PlanarDiagram)

Return the number of link components in a planar diagram.

This function determines the number of connected components (link components) in a given planar diagram representation of a link. For example, a trefoil knot has 1 component, while the Hopf link consists of 2 components.

Args:

k: The input planar diagram representing the link, from which

the number of components will be derived.

Returns:

int: The number of link components present in the given planar diagram.
