話說從前有100個農夫犯了死罪,國王要將他們全部處死!!!
但是國王行刑的方式很特別,他把農夫排成一直線,全部向前看,然後國王會在每人頭上戴
一頂帽子, 帽的顏色是紅, 黃或者綠的...
由於100人排成直線,排最後的那個人可以看到前面全部99人的帽的顏色,倒數第二那個就
可以看到前面98人的帽子的顏色,如此類推,.而第二人只能看到第一人的帽子的顏色.第一
人就什麼也看不到, 而這國王要農夫們逐個猜自己頭上帽子的顏色,.猜中就不用死,.答錯
便會被殺, 然後下一個答...
而農夫只准許說一個字的答案: "紅", "黃"或者 "綠" ,若有人說其他任何形式的答案的
話就100人全部都要死!!!!
農夫們希望將犧牲的人數減到最少,於是向國王提議讓他們自己商量一陣,
國王認為這些農夫再怎麼討論都不會有什麼結果, 於是就答應他們...還答應讓農夫們自
己決定回答的次序,.等農夫們商量完, 排成直線之後, 把帽子戴上在他們頭上...然後開
始回答...
請問農夫們最好的方案是什麼?
