For i = 1, 2, dots, n i=1,2,…,n, at the beginning of i-th round Rikka's aggressivity A increases by the increment D, and then she can do one of the following: ·Attack and cause a damage of (A + a_i) (A+a i ). ·Use the Omnipotent Garland from LCR to increase the increment D by b_i b i . ·Use her Schwarz Sechs Prototype Mark II to increase the aggressivity A by c_i c i . Rikka wonders the maximal possible damage she could cause in total. Could you help her?
