* ok, not so simple
|
|
'how to find 3 edges which if removed split graph into 2 components'
|
|
|
|
i guess i could find all cycles?
|
|
and then what?
|
|
|
|
then if i have graph without cycles and all of the removed edges,
|
|
maybe i can figure out how to remove one edge, to make two components, and all (k - 2) edges back in a way that would not connect those components.
|
|
|
|
well, the cycles maybe should have been broken elsewhere?
|
|
for most cycles - it doesn't matter.
|
|
|
|
for cycles that break into 2 components, does it?
|
|
|
|
ok. if i have the no-cycle graph.
|
|
then we can maybe start searching for 'third' edge to remove.
|
|
|
|
i remove it, i get two components.
|
|
then as a test - exactly two edges when added should connect those components.
|
|
if that happens - i have an answer
|
|
|
|
sounds good
|
|
** making code to get components.
|
|
now.
|
|
** make method to remove all cycles.
|
|
save the removed edges to slice
|
|
|
|
i guess could be a method that modifies the graph and returns all removed edges.
|
|
and test that
|
|
** why a node ends up without any edges?
