Given that:
expression state at time 18 = "iterate_args"
arguments stack at time 18 = [ [ "Mexico", [ ] ], [ [ ], [ ] ] ]
parent stack at time 18 = [ entry "MX": "Mexico", [
{"ES": "Estonia", "MX": "Mexico"}, [ ] ] ]Prove that:
parent stack at time 19 = [ entry "MX": "Mexico", [
{"ES": "Estonia", "MX": "Mexico"}, [ ] ] ]The following properties may be helpful:
- 18 + 1 = 19
if the following are true:
- expression state at time t = "iterate_args"
- arguments stack at time t = [ [ x, y ], z ]
then parent stack at time (t + 1) = parent stack at time t
if the following are true:
- a = b
- b = c
then a = c
if 18 + 1 = 19, then parent stack at time (18 + 1) = parent stack at time 19
if the following are true:
- a = b
- a = c
then b = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
