. For any integer n ≥ 2, let A(n) denote the number of ways to fully parenthesize a sum of n terms such as a1 + · · · + an. Examples: • A(2) = 1, since the only way to fully parenthesize a1 + a2 is (a1 + a2). • A(3) = 2, since the only ways to fully parenthesize a1 + a2 + a3 are ((a1 + a2) + a3) and (a1 + (a2 + a3)). • A(4)...
