Hello....I didn`t read all the answers.but if we concider the colors as 0 and 1
now let us take any random possibilty...e.g
00111000111001110011
the first one(0)has 50% survival chance,,but he will say the color seeing in the front of him,,,in this case (0)
the second one (he knew now his color),at the same time he saw the color in front of him (1),which is different color
so he will wait shortly then he`ll say his color(0).
the 3rd(is sure now that he has (1),because the 2nd didn`t said immediatly,,0).
and as the person infront of him has also (1)in this example,so he will say his color(1) immediatly!
and so on!
so...
1st....(o)
2nd.............(0)
3rd....(1)
4th....(1)
5th.............(1)
6th....(0)
