Problem Description: Given n integer sequence {a1,a2,..., an}, function f (i,j) =max{0,σak} (k: Continuous from I to j);
The problem is the maximum value of the continuous sub-columns, if the maximum is negative, take 0, such as 8 number sequence { -1,2,-3,4,-2,5, -8,3}, the maximum subsequence and the 4+ (-2) +5=7.
This problem has four different complexity algorithms, the time complexity of the algorithm 1 to four is O (N3), O (N2), O (Nlogn), O (n);

To meet the functional requirements, we have written the following six functions:

The question is good, 1234. The proposal is very simple. Now I will give you a few sets of data and ask you to find the people who open the door and close the door. Click the link below to open the link. It is actually the string processing of water and water, but the intensity of string is more than that. In a few days, the provincial competition will come back and write a new one. Because string will appear in any competition, stl and string functions are more popular with acmer.
