Exercise 2: Download the file secret image.bmp from the course website and display the image. This image has been purposely modified in an attempt to conceal a hidden image. First the pixel values were all divided by 10, so the range of the data was reduced to the range 0 to 26. Then the value 200 was added to about half of the pixels which were selected at random. This processing covers the original image with random noise, however, it is possible to remove the processing and recover the original image. The pixels that were randomly selected will have values greater than 26, so in order to recover the original image, a program needs to check each pixel value, and for those pixels that have a value greater than 26, the program should subtract 200. Then the program should multiply all pixel values by 10. Write a script file that loads secret_image.bmp, recovers the original image, and displays the result
