A. (WARMUP] Implement the function empty that takes nrows (the number of cow's of pixels), and cols the number of pixels in each rows as inputs. It outpuls a lux of size nrows by ncols with all its elements equal to zero 12 marks Acolourell image (RGB image is intensity of every pixel for the three channels, namely real, geen, and blue. Every pixel value is a decimal number between Valid 1. O quantities the channel at its lowest intensity and I quantifies the channel at its highest intensity.
