Proof: Get Iterate End Expr 30
Let's prove the following theorem:
if the following are true:
- expression state at time 30 = "iterate_args"
- arguments stack at time 30 = [ [ ], [ ] ]
- parent stack at time 30 = [ self."y" = 0, [ ] ]
then the expression at time 31 = self."y" = 0
Proof:
Given
1 | expression state at time 30 = "iterate_args" |
---|---|
2 | arguments stack at time 30 = [ [ ], [ ] ] |
3 | parent stack at time 30 = [ self."y" = 0, [ ] ] |
# | Claim | Reason |
---|---|---|
1 | the expression at time (30 + 1) = self."y" = 0 | if expression state at time 30 = "iterate_args" and arguments stack at time 30 = [ [ ], [ ] ] and parent stack at time 30 = [ self."y" = 0, [ ] ], then the expression at time (30 + 1) = self."y" = 0 |
2 | 30 + 1 = 31 | 30 + 1 = 31 |
3 | the expression at time (30 + 1) = the expression at time 31 | if 30 + 1 = 31, then the expression at time (30 + 1) = the expression at time 31 |
4 | the expression at time 31 = self."y" = 0 | if the expression at time (30 + 1) = the expression at time 31 and the expression at time (30 + 1) = self."y" = 0, then the expression at time 31 = self."y" = 0 |
