Given that:
the line at time 45 = 3
the tab at time 45 = 1
statement at line 3, tab 1 =
a = __add__(a, 1)
expression state at time 45 = "end_expr"
Prove that:
the tab at time 46 = 1
The following properties may be helpful:
- 45 + 1 = 46
if the following are true:
- the line at time t = i
- the tab at time t = j
- statement at line i, tab j = assign statement with target x and expression (function call with name: name and arguments: args)
- expression state at time t = "end_expr"
then the tab at time (t + 1) = the tab at time t
if the following are true:
- a = b
- b = c
then a = c
if 45 + 1 = 46, then the tab at time (45 + 1) = the tab at time 46
if the following are true:
- a = b
- a = c
then b = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
