A milk carton can hold 3.78 liters of milk. Each morning, a dairy farm ships cartons of milk to a local grocery store. The cost of producing one liter of milk is 0.38, and the profit of each carton of milk is 0.27.

You are given an array of N non-negative integers: A₁, A₂, ..., A_N. An alternating subsequence is a subsequence in which the indices of any two consecutive elements differ by exactly two in the original array. That is, if A_i1, A_i2, ..., A_ik is some subsequence, then for it to be an alternating subsequence, (i₂ - i₁ = 2), (i₃ - i₂ = 2), and so on should all hold true. Among all alternating subsequences, find the one which has maximum sum of elements, and output that sum.

An egg distribution company uses different sizes of packings for eggs, that is, 30 eggs packing, 24 eggs packing, 18 eggs packing, 12 eggs packing and 6 eggs packing.
