Write the "top-level" of a program to perform one cycle of a trafic light. This cycle will have three phases, a green phase, a yellow phase, and a red phase. Do the following.
- Precisely type
cycle = (green)phase, (yellow)phase, (red)phase
followed by the Return key in the Blue Clay Text Input Field.
Note that this is an incomplete or unrefined definition of the cycle program. Consequently, it must be refined before it can be run.
So, refine the cycle program.
