You are given a binary array with N elements: d[0], d[1], ... d[N - 1]. You can perform AT MOST one move on the array: choose any two integers [L, R], and flip all the elements between (and including) the L-th and R-th bits. L and R represent the left-most and right-most index of the bits marking the boundaries of the segment which you have decided to flip.What is the maximum number of '1'-bits (indicated by S) which you can obtain in the final bit-string?'Flipping' a bit means, that a 0 is transformed to a 1 and a 1 is transformed to a 0 (0->1,1->0). Input Format:An integer N,Next line contains the N bits, separated by spaces: d[0] d[1] ... d[N - 1]
