Consider the following 2D array of objects: Pixel screen[Y_DIM] [X_DIM]; Class Pixel has a setColor (int color) member function to set the color of a pixel (it returns nothing) and a default constructor that makes the pixel's color black. Use this array for the next 4 questions. Question 4 1 pts Suppose Y_DIM IS 3 and X_DIM IS 2. Recall how 2D arrays are laid out in 1D memory. Which index in 1D memory would give you screen [2] [0]? Assume the first 1D element is at index 0
