Place letters A to H on nodes such that:

• Each letter appears exactly once.
• Consecutive letters do not appear on adjacent nodes.
• Consecutive letters are letters that follow one another in the alphabet (e.g., A and B, B and C).
• Adjacent nodes are those that are connected with an edge.

Drag and drop the letters to solve the puzzle. Violated constraints will be marked using a red edge. You can drag letters back to the deck at the bottom if needed.
