Use Processing to write and test code that meets the requirements below.
1-Create a 600x400 window with a green background (using 64 as the "amount" of green to draw).
2-Within the draw() function, detect keyboard events for each letter of the alphabet (including both uppercase and lowercase letters).
3-For each letter pressed by the user, display a line-drawing of the letter at the current mouse location. Letters can be any color you like (for example, try red 255, green 255, blue 210). Use a stroke weight of 5 and specify "ROUND" for the strokeCap() function. Note that you may display a capital-A for both 'a' and 'A' if you'd like
4-For extra credit, also display lowercase letters and numeric digits.
5-For extra extra credit, use CTRL-R to erase the screen and start over. Further, use CTRL-C to change the stroke color to a random color.
