Proof: Get Iterate Params 54
Let's prove the following theorem:
if the following are true:
- expression state at time 54 = "iterate_args"
- arguments stack at time 54 = [ [ 5, [ ] ], [ [ ], [ ] ] ]
then arguments stack at time 55 = [ [ ], [ [ ], [ ] ] ]
Proof:
Given
1 | expression state at time 54 = "iterate_args" |
---|---|
2 | arguments stack at time 54 = [ [ 5, [ ] ], [ [ ], [ ] ] ] |
# | Claim | Reason |
---|---|---|
1 | arguments stack at time (54 + 1) = [ [ ], [ [ ], [ ] ] ] | if expression state at time 54 = "iterate_args" and arguments stack at time 54 = [ [ 5, [ ] ], [ [ ], [ ] ] ], then arguments stack at time (54 + 1) = [ [ ], [ [ ], [ ] ] ] |
2 | 54 + 1 = 55 | 54 + 1 = 55 |
3 | arguments stack at time (54 + 1) = arguments stack at time 55 | if 54 + 1 = 55, then arguments stack at time (54 + 1) = arguments stack at time 55 |
4 | arguments stack at time 55 = [ [ ], [ [ ], [ ] ] ] | if arguments stack at time (54 + 1) = arguments stack at time 55 and arguments stack at time (54 + 1) = [ [ ], [ [ ], [ ] ] ], then arguments stack at time 55 = [ [ ], [ [ ], [ ] ] ] |
