The Gaussian Transform

CodeChefOpen on judge ↗

You have been given the details of an image in a list where each index shows the usefulness of the pixel. The smoothness of the image depends on the maximum subarray sum of pixel values. One of the good techniques to smoothen the image is to use the Gaussian Transform, which alters the sign of at most two pixel values. Find the maximum smoothing value you can achieve by using the Gaussian T
