Proof step 9 from proof getarray-offset (previous step)

¬ j ≤ 0, 0 ≤ j, 0 ≤ j0, j0 ≤ 1, j ≤ 1, j0 ≤ j, ∀ j1, j0, r, i, st. i→n(j1) < i→n(j) → (j0 ≤ j1 ∧ 0 ≤ j0 → getarray(r, i, j1, st) = getarray(r, i, j0, st) + getarray(r, i + j0, j1 - j0, st)) ⊦ getarray(r, i, j, st) = getarray(r, i, j0, st) + getarray(r, i + j0, j - j0, st)

And obtained the following new goals

Proof step 3:
⊦ getarray(r, i, 1, st) = st[r -- i '] '
Proof step 8:
0 ≤ j0, j0 ≤ 1, ∀ j1, j0, r, i, st. i→n(j1) < i→n(1) → (j0 ≤ j1 ∧ 0 ≤ j0 → getarray(r, i, j1, st) = getarray(r, i, j0, st) + getarray(r, i + j0, j1 - j0, st)) ⊦ st[r -- i '] ' = getarray(r, i, j0, st) + getarray(r, i + j0, 1 - j0, st)
