WebFeb 20, 2024 · Method 1 (Simple : O (n2)): A simple solution is to consider all subarrays and find a subarray with maximum value of (count of 1s) – (count of 0s). Let this value be max_diff. Finally, return count of zeros in original array plus max_diff. As constant extra space is used. Method 2 (Efficient : O (n)): This problem can be reduced to largest ...
