Description

another possible solution to minimize the number of dwarves killed is as follows: each dwarf has to say 'black' or 'white'. Each dwarf speaks the color of the hat being worn by the dwarf in front of him/her. This way, only the first dwarf shall be killed in the worst case. All other dwarves shall know the color of their hat, for certainty.

Am I missing something ? it feels lot more simpler solution as compared with computing parity
