问题 A rectangle is defined as any rectangular-shaped section of zeros within a 2-d array of 1s and 0s. Typical example: [ [1, 1, 1, 1, 1, 1, 1, 1, 1], [1, 1, 1, 1, 1, 1, 1, 1, 0], [1, 1, 1, 0, 0, 0, 1, 0, 0], [1, 0, 1, 0, 0, 0, 1, 0, 0], [1, 0, 1, 1, 1, 1, 1, 1, 1], [1, 0, 1, 0, 0, 1, 1, 1, 1], [1, 1, 1, 0, 0, 1, 1, 1, 1], [1, 1, 1, 1, 1, 1, 1, 1, 1], ] In this example, there are three such arrays: My goal is to determine the coordinates (outer 3 extremeties) of each array. I start by converting
