What is a code to maximize the sum of array by multiplying prefix of array with and the other steps required given the following:
Maximize the sum of array by multiplying prefix of array with | Python implementation of the approach.
To store sum.
To store ending indices of the chosen prefix arrays.
Adding the absolute value of a [ i ].
If i == 0 then there is no index to be flipped in ( i - 1 ) position.
print the maximised sum.
print the ending indices of the chosen prefix arrays.
Driver Code"
How can the above be solved in Python?
