/*
D=3 N
all nodes have indegree N-1
D=2
OBSERVE:
Graph is connected
if 2 nodes are not connected all other nodes are connected to them
degree in N-1 or N-2
man kann immer zwischen 2er paaren huepfen
D=1
OBSERVE
    if 2 nodes are not connected all other nodes are connected to either node
find longest path ?
consider a connected component what can we say about it
    can we always find a path of length == SZ(component)
connected component
    add a node
    if there are 2 nodes not conneced then new node also has to be connected there
