• result of storing 2 at key: a in map: [ entry a: 1, [ ] ] = [ entry a: 2, [ ] ]
• 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 Variables Map at time (t + 1) = result of storing (Return Value at time t) at key: x in map: (Variables Map at time t)

• if Return Value at time 45 = 2, then result of storing (Return Value at time 45) at key: a in map: (Variables Map at time 45) = result of storing 2 at key: a in map: (Variables Map at time 45)

• if the following are true:

  • a = b
  • b = c

  then a = c

• if Variables Map at time 45 = [ entry a: 1, [ ] ], then result of storing 2 at key: a in map: (Variables Map at time 45) = result of storing 2 at key: a in map: [ entry a: 1, [ ] ]

• if the following are true:

  • a = b
  • b = c

  then a = c

• if the following are true:

  • a = b
  • b = c

  then a = c

• if 45 + 1 = 46, then Variables Map at time (45 + 1) = Variables Map 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.
