Proof: Get Iterate End Parent 47

Let's prove the following theorem:

if the following are true:
  • expression state at time 47 = "iterate_args"
  • arguments stack at time 47 = [ [ ], [ ] ]
  • parent stack at time 47 = [ self."age" = age, [ ] ]

then parent stack at time 48 = [ ]

Given
1 expression state at time 47 = "iterate_args"
2 arguments stack at time 47 = [ [ ], [ ] ]
3 parent stack at time 47 = [ self."age" = age, [ ] ]
Proof Table
# Claim Reason
1 parent stack at time (47 + 1) = [ ] if expression state at time 47 = "iterate_args" and arguments stack at time 47 = [ [ ], [ ] ] and parent stack at time 47 = [ self."age" = age, [ ] ], then parent stack at time (47 + 1) = [ ]
2 47 + 1 = 48 47 + 1 = 48
3 parent stack at time (47 + 1) = parent stack at time 48 if 47 + 1 = 48, then parent stack at time (47 + 1) = parent stack at time 48
4 parent stack at time 48 = [ ] if parent stack at time (47 + 1) = parent stack at time 48 and parent stack at time (47 + 1) = [ ], then parent stack at time 48 = [ ]
