(Hint: There is a pirate can get 98% of gold)
A 1: 98,0,1,0,1
premier start from the No. 5 Pirates, because he is the most secure, the hazard of the sea has not been dropped, so he is also the most easy tactics, that is the best human in front of all die out, then he can get it lonely 100 gold coins.
then see 4, his accidents of survival depends entirely on the person in front of there alive, because if 1 to 3 of the pirates were all fed a shark, then merely 4 and 5 in the case, regardless of 4 on what the distribution plan, some will vote opposition the No. 5 to permit sharks to feed 4 to pocketed all of the coins. Even 4 to 5, amuse retention your life and made (0,100) This exclusive program because 5 gold, but keep the No. 5 No. 4 may also feel that there is peril, and voted against and let it feed the sharks. Therefore, a rational 4 should not take such a risk, the survival of wish in a promiscuous choice of 5, he can only patronize 3 in order to indeed assure their own lives.
look at No. 3, he followed through the logic of reasoning, it will make (100,0,0) this allocation scheme, because he knows naught even 4, it will unconditionally support or vote for him , then combined with their one vote can make him sure to triumph the 100 gold coins.

A: 14. Let x egg throwing to test the F layer y times, then F = f (x, y). f (1,1) = 1, f (1,2) = 2 ... ... .. f (1, n) = n. f (2,1) = 1, for f (2,2), the first test time, if the first egg is not broken, then test the layer on altitude of layers of f (2,1), if the first break an egg , and then test the layer beneath the layers of f (1,1), so f (2, n) = 1 + f (1, n-1) + f (2,Nike Shox Dreams, n-1). Thus f (2,1) = 1, f (2,2) = 3, f (2,3) = 6, f (2,4) = 10, f (2,5) = 15, f (2, 6) = 21. Introduction of series: f (2, n) = n * (n +1) / 2. The solution, n = 14.
