Proof step 11 from proof getbar-add-01 (previous step)

0 < j, ∀ st, vals, ty, i, r0, r, j0. i→n(j0) < i→n(j) → (true → r = r0 ∨ getbytearray(r, i, j0, addarray(r0, ty, vals, st)) = getbytearray(r, i, j0, st)) ⊦ r = r0, st[r -- i '] .byteval ' + getbytearray(r, i + 1, j - 1, addarray(r0, ty, vals, st)) = getbytearray(r, i, j, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 10:
j = i0 + 1, 0 < j, ∀ st, vals, ty, i, r0, r, j0. i→n(j0) < i→n(j) → (true → r = r0 ∨ getbytearray(r, i, j0, addarray(r0, ty, vals, st)) = getbytearray(r, i, j0, st)) ⊦ r = r0, st[r -- i '] .byteval ' + getbytearray(r, i + 1, i0, addarray(r0, ty, vals, st)) = getbytearray(r, i, j, st)
