Consider the following program:

Perform at least the following optimizations:

• Removal of the if in the innermost loop (line 14)
• Loop unrolling (line 13)
• Constant propagation
• Floating-point to fixed-point conversion
• Avoidance of all accesses to arrays

Please provide the optimized version of the program after each of the transformations and do also check for consistent results!
