Proof step 74 from proof putarray-addarray-override (previous step)

¬ (0 ≤ i0 ∧ i0 < n→i(# vals0)), i0 < 0, i + n→i(# vals) ≤ n→i(# vals0), 0 ≤ i ⊦ (addarray(r0, ty, vals0, st)[r0 -- i0 ']) = st[r0 -- i0 ']

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 73:
i0 < 0, i + n→i(# vals) ≤ n→i(# vals0), 0 ≤ i ⊦ (addarray(r0, ty, vals0, st)[r0 -- i0 ']) = st[r0 -- i0 ']
