Question 3(5 points). For grad students. There are piles of
coins on the table. The number of coins in each pile is known.
Please pick up piles to maximize the number of coins. The
restriction is that you cannot pick up coins from consecutive two
piles. The last pile and the first pile ARE connected. For example,
when you pick up the first one, you cannot pick up the last one. Or
when you pick up the last one, you cannot pick up the first one.
Using other methods will not receive any credit.
