( 1682 ) | F | Bear and Bowling 4 | PROGRAMMING | binary search data structures geometry ternary search | 2500 |
B"Limak is an old brown bear. He often goes bowling with his friends. Today he feels really good and tries to beat his own record! For rolling a ball one gets a score -- an integer (maybe negative) number of points. Score for the i-th roll is multiplied by i and scores are summed up. So, for k rolls with scores s1, xe2 x80 x89s2, xe2 x80 x89..., xe2 x80 x89sk, the total score is . The total score is 0 if there were no rolls. Limak made n rolls and got score ai for the i-th of them. He wants to maximize his total score and he came up with an interesting idea. He can say that some first rolls were only a warm-up, and that he wasn't focused during the last rolls. More formally, he can cancel any prefix and any suffix of the sequence a1, xe2 x80 x89a2, xe2 x80 x89..., xe2 x80 x89an. It is allowed to cancel all rolls, or to cancel none of them. The total score is calculated as if there were only non-canceled rolls. So, the first non-canceled roll has score multiplied by 1, the second one has score multiplied by 2, and so on, till the last non-canceled roll. What maximum total score can Limak get? The first line contains a single integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x892 xc2 xb7105) -- the total number of rolls made by Limak. The second line contains n integers a1, xe2 x80 x89a2, xe2 x80 x89..., xe2 x80 x89an (|ai| xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89107) -- scores for Limak's rolls. Print the maximum possible total score after cancelling rolls. In the first sample test, Limak should cancel the first two rolls, and one last roll. He will be left with rolls 1, xe2 x80 x89 xe2 x80 x89- xe2 x80 x893, xe2 x80 x897 what gives him the total score 1 xc2 xb71 xe2 x80 x89+ xe2 x80 x892 xc2 xb7( xe2 x80 x89- xe2 x80 x893) xe2 x80 x89+ xe2 x80 x893 xc2 xb77 xe2 x80 x89= xe2 x80 x891 xe2 x80 x89- xe2 x80 x896 xe2 x80 x89+ xe2 x80 x8921 xe2 x80 x89= xe2 x80 x8916."... |
