Proof: Get Iterate End Expr 31
Let's prove the following theorem:
if the following are true:
- expression state at time 31 = "iterate_args"
- arguments stack at time 31 = [ [ ], [ ] ]
- parent stack at time 31 = [ self."first_name" = first_name, [ ] ]
then the expression at time 32 = self."first_name" = first_name
Proof:
Given
1 | expression state at time 31 = "iterate_args" |
---|---|
2 | arguments stack at time 31 = [ [ ], [ ] ] |
3 | parent stack at time 31 = [ self."first_name" = first_name, [ ] ] |
# | Claim | Reason |
---|---|---|
1 | the expression at time (31 + 1) = self."first_name" = first_name | if expression state at time 31 = "iterate_args" and arguments stack at time 31 = [ [ ], [ ] ] and parent stack at time 31 = [ self."first_name" = first_name, [ ] ], then the expression at time (31 + 1) = self."first_name" = first_name |
2 | 31 + 1 = 32 | 31 + 1 = 32 |
3 | the expression at time (31 + 1) = the expression at time 32 | if 31 + 1 = 32, then the expression at time (31 + 1) = the expression at time 32 |
4 | the expression at time 32 = self."first_name" = first_name | if the expression at time (31 + 1) = the expression at time 32 and the expression at time (31 + 1) = self."first_name" = first_name, then the expression at time 32 = self."first_name" = first_name |
