Proof: Get Iterate Params 13
Let's prove the following theorem:
if the following are true:
- expression state at time 13 = "iterate_args"
- arguments stack at time 13 = [ [ "Smith", [ 25, [ ] ] ], [ ] ]
then arguments stack at time 14 = [ [ 25, [ ] ], [ ] ]
Proof:
Given
1 | expression state at time 13 = "iterate_args" |
---|---|
2 | arguments stack at time 13 = [ [ "Smith", [ 25, [ ] ] ], [ ] ] |
# | Claim | Reason |
---|---|---|
1 | arguments stack at time (13 + 1) = [ [ 25, [ ] ], [ ] ] | if expression state at time 13 = "iterate_args" and arguments stack at time 13 = [ [ "Smith", [ 25, [ ] ] ], [ ] ], then arguments stack at time (13 + 1) = [ [ 25, [ ] ], [ ] ] |
2 | 13 + 1 = 14 | 13 + 1 = 14 |
3 | arguments stack at time (13 + 1) = arguments stack at time 14 | if 13 + 1 = 14, then arguments stack at time (13 + 1) = arguments stack at time 14 |
4 | arguments stack at time 14 = [ [ 25, [ ] ], [ ] ] | if arguments stack at time (13 + 1) = arguments stack at time 14 and arguments stack at time (13 + 1) = [ [ 25, [ ] ], [ ] ], then arguments stack at time 14 = [ [ 25, [ ] ], [ ] ] |
