Remember graph coloring problem in the problem session.
(a) Draw the graph of the following code block.
(b) Explain how you represent the components of the code in graph coloring problem.
(c) What is the minimum number of registers that you need to compile the code? Show which variables can be
in the same register.
Line 1: a = 3
Line 2: b = 6
Line 3: c = 4
Line 4: d = b + c
Line 5: e = d + a
Line 6: if e < 4="" then="" f="4" ="">
Line 7: else then f = 6  a
Line 8: d = f - c
