"I’ve tried everything," Leo admitted, his voice cracking. "Inductive steps, contradiction, even checking the Handshaking Lemma just to feel like I knew something . There’s no solution manual for this in the back."
If a proof involves coloring or planarity, isolate parts of the graph. If you can find a core structure that violates a rule, the entire graph violates it.
