Proof step 8 from proof copy-upper (previous step)

i0 + j ≤ j0 ⊦ (arraycopy(r, i, r0, i0, j, st)[r0 -- j0 ']) = st[r0 -- j0 ']

User applied rule induction

And obtained the following new goals

Proof step 7:
i0 + j ≤ j0, ∀ j1, i0, j0, r, i, r0, st. i→n(j1) < i→n(j) → (i0 + j1 ≤ j0 → (arraycopy(r, i, r0, i0, j1, st)[r0 -- j0 ']) = st[r0 -- j0 ']) ⊦ (arraycopy(r, i, r0, i0, j, st)[r0 -- j0 ']) = st[r0 -- j0 ']

Rule argument

[INDHYPARG : [STANDARDINDUCTIONTYPE : ], true, false, i→n(j), [] → [], <]
