In the evening, Father Benson normally experiments in his laboratory. However, this evening was different. His goal for the night was to extinguish all 7 candles in his room. These candles were marked 1-7 and mistakenly enchanted. When he blew out the first one, candles 7 and 2 were blown out as well! When he blew on the first one again, all three candles were relit! He repeated blowing on other candles and it seems blowing on one candle will change the state of 3 (it and it’s neighbors). What is the least amount of times he needs to blow on the candles to extinguish all of them? What is that sequence?
