In this problem you don't discard all end of year inventory. The place
where you get extra M&Ms when you need them is like a very big
reservoir that has some fixed capacity C. In this problem, we are
essentially assuming that C is large enough that it can cover the
deficit from all the years. We will let c(i) denote the number of M&Ms
in the reservoir in the ith year. The goal is to find the maximum
value of B such that c(n) = C. You only discard M&Ms when the excess,
i.e. A_i - B) + c(i-1) > C (which is the excess that the reservoir
cannot contain).
