Random Shape
Create a program that, for a given number of times, displays a shape (e.g., a triangle, circle, etc.) at random locations on the drawing canvas. For example, the user may specify that the shape should be displayed 5 times, or 7 times, etc. For every appearance of the shape's image at a new location, the previous shape's image should disappear - that is, at any given time there should be only one shape displayed on the canvas.
