Thanks that cleared up a lot.(Original post by matthewdownloads)
On the top graph (Q3) you drew in the isolated noes and edges only (the "subgraph") with the red/blue switched round.
On the graph below that, you drew everything including the new switched colours AND the orange/yellow replaced with the appropriate red/blue colours.
Maybe this will clear it (quick summary of it):
Of course, the graph went vertically as well in the same way^ rather than just horizontally like I wrote above.Code:Basically if I said, get a string of 5 letters which can't have 2 consecutive letters the same, using B and R: Original letters (original graph): RBYBR So isolate the relevant letters ("Draw the subgraph") RB BR Switch them round ("Switch colours with 2 or more nodes") BR RB Add the appropriate letter to replace Y ("Show the graph can be done in two colours") BRBRB
