Proof: Get Iterate Parent 36
Let's prove the following theorem:
if the following are true:
- expression state at time 36 = "iterate_args"
- arguments stack at time 36 = [ [ last_name, [ ] ], [ ] ]
- parent stack at time 36 = [ self."last_name" = last_name, [ ] ]
then parent stack at time 37 = [ self."last_name" = last_name, [ ] ]
Proof:
Given
1 | expression state at time 36 = "iterate_args" |
---|---|
2 | arguments stack at time 36 = [ [ last_name, [ ] ], [ ] ] |
3 | parent stack at time 36 = [ self."last_name" = last_name, [ ] ] |
# | Claim | Reason |
---|---|---|
1 | parent stack at time (36 + 1) = parent stack at time 36 | if expression state at time 36 = "iterate_args" and arguments stack at time 36 = [ [ last_name, [ ] ], [ ] ], then parent stack at time (36 + 1) = parent stack at time 36 |
2 | parent stack at time (36 + 1) = [ self."last_name" = last_name, [ ] ] | if parent stack at time (36 + 1) = parent stack at time 36 and parent stack at time 36 = [ self."last_name" = last_name, [ ] ], then parent stack at time (36 + 1) = [ self."last_name" = last_name, [ ] ] |
3 | 36 + 1 = 37 | 36 + 1 = 37 |
4 | parent stack at time (36 + 1) = parent stack at time 37 | if 36 + 1 = 37, then parent stack at time (36 + 1) = parent stack at time 37 |
5 | parent stack at time 37 = [ self."last_name" = last_name, [ ] ] | if parent stack at time (36 + 1) = parent stack at time 37 and parent stack at time (36 + 1) = [ self."last_name" = last_name, [ ] ], then parent stack at time 37 = [ self."last_name" = last_name, [ ] ] |
