Write a Processing program that allows the user to toggle between pictures of a surprised face and an angry face. When your program starts, it should display a picture of a surprised face. Whenever the user clicks the mouse, it should display and angry face $($if an angry face was already displayed, well then it should keep displaying an angry face$).$ Whenever the user presses any key, it should display a surprised face $($again$,$ regardless of whether a surprised face was already being displayed$).$ In this way, the user can toggle back and forth between the pictures of the two faces as many times as they like.

To achieve this, and practice using functions in a useful way, you should define a function called draw$\_$face $(),$ with the following $6$ parameters:

r$\_$face, g$\_$face, b$\_$face: $3$ integers, representing RGB color values for the face's colour

r$\_$brows, g$\_$brows, b$\_$brows: $3$ integers, representing RGB color values for the face's eyebrows

Whenever you need to draw either of the faces, your code should call this function. Don't create a different function for each face, simply call this one with different values for the arguments. $($hint: If you don't want the eyebrows to be visible, what color should they be in relation to the face colour?$)$

Your pictures of the two faces need not look exactly like the sample, but you should make a reasonable attempt at aesthetic appeal.

Hint: You may find the strokeWeight $()$ function useful to draws lines of different thickness.
