🧪 The LCA Liquid Mixer

Blue liquid rises from node A, red liquid rises from node B — both climbing one parent at a time. The instant a single node has been touched by both colors, they mix to purple right there. That node is the Lowest Common Ancestor.

🔵 Blue LiquidI only ever climb upward, one parent at a time. I never go back down, and I never skip a level.
🔴 Red LiquidThe moment I touch a node blue already reached — or blue touches one I already reached — we mix. That node is the answer.
Pick a level above to begin.
