We will determine brightness as the point (i,j) in the x by y image where the sum of red[i][j], green[i][j] and blue[i][j] is the greatest.

The body calls the method brightSpot() and based on the input, prints out the following:

"The brightest spot in the image is at position (i,j)"

The brightSpot() method will take the following parameters:

three x by y integer arrays, which we will call red, green and blue to represent the red, green and blue present in the image.

Processing

Based on the definition of brightness given above, the method will determine the brightest spot (i,j) in the image.

Output

The brightSpot() method will return an integer array containing the brightest spot (i,j).
