Proof: Do Stack At Unchanged 35

Let's prove the following theorem:

if the following are true:
  • expression state at time 35 = "iterate_args"
  • stack at time 35 = [ ]

then stack at time 36 = [ ]

Given
1 expression state at time 35 = "iterate_args"
2 stack at time 35 = [ ]
Proof Table
# Claim Reason
1 stack at time (35 + 1) = stack at time 35 if expression state at time 35 = "iterate_args", then stack at time (35 + 1) = stack at time 35
2 stack at time (35 + 1) = [ ] if stack at time (35 + 1) = stack at time 35 and stack at time 35 = [ ], then stack at time (35 + 1) = [ ]
3 35 + 1 = 36 35 + 1 = 36
4 stack at time (35 + 1) = stack at time 36 if 35 + 1 = 36, then stack at time (35 + 1) = stack at time 36
5 stack at time 36 = [ ] if stack at time (35 + 1) = stack at time 36 and stack at time (35 + 1) = [ ], then stack at time 36 = [ ]
