Proof step 8 from proof addobj-getarray-01 (previous step)

0 < j, ∀ st, fis, class, i, r0, r, j0. i→n(j0) < i→n(j) → (true → r = r0 ∨ getarray(r, i, j0, addobj(r0, class, fis, st)) = getarray(r, i, j0, st)) ⊦ getarray(r, i, j, addobj(r0, class, fis, st)) = st[r -- i '] ' + getarray(r, i + 1, j - 1, st), r = r0

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
j = i0 + 1, 0 < j, ∀ st, fis, class, i, r0, r, j0. i→n(j0) < i→n(j) → (true → r = r0 ∨ getarray(r, i, j0, addobj(r0, class, fis, st)) = getarray(r, i, j0, st)) ⊦ getarray(r, i, j, addobj(r0, class, fis, st)) = st[r -- i '] ' + getarray(r, i + 1, i0, st), r = r0
