Edit the loop my_loop in the exercise below so that it starts by writing 10 to [ap], continues by writing the decreasing sequence and then returns. Don’t forget the ret instruction. Verify that your code works as expected by looking at the memory.
func main():
[ap] = 2; ap++
my_loop:
[ap] = [ap - 1] * [ap - 1]; ap++
[ap] = [ap - 1] + 1; ap++
jmp my_loop
end
What does the following code do? (run with –no_end –step=16 to avoid the End of program was not reached error)
func main():
[ap] = 2; ap++
my_loop:
[ap] = [ap - 1] * [ap - 1]; ap++
[ap] = [ap - 1] + 1; ap++
jmp my_loop
end
What’s wrong with the following code?
func main():
[ap] = 300
[ap + 10000000000] = 400
ret
end
Run the following program:
func main():
[ap] = 100
[ap + 2] = 200
ret
end
Explain why the execution of this program creates a memory gap, and therefore an inefficiency (given what you’ve just read in the above section). Add one instruction at the end of the function (just before ret) so that there won’t be a memory gap.

Write a program poly.cairo that computes the expression x^3 + 23*(x^2) + 45*x + 67 where x = 100
func main():
[ap] = 100; ap++
# << Your code here >>
ret
end
