Proof step 115 from proof addarray-put-01 (previous step)

0 ≤ i0 ⊦ (addarray(r, ty, 1 + i0, st)[r -- i ']) = (addarray(r, ty, val ' + mklist(initial_value(ty), i→n(i0)), st)[r -- i ']), i = 0, ¬ i < 0 ∧ ¬ i0 < i

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 111:
⊦ i < 0 ∨ n→i(# vals) ≤ i → (addarray(r, ty, vals, st)[r -- i ']) = st[r -- i ']
Proof step 114:
i < 0 ∨ n→i(# (val ' + mklist(initial_value(ty), i→n(i0)))) ≤ i, 0 ≤ i0 ⊦ (addarray(r, ty, 1 + i0, st)[r -- i ']) = st[r -- i '], i = 0, ¬ i < 0 ∧ ¬ i0 < i

Rule argument

[crewrite-arg: add-at-other-index , F , [i, st, vals, ty, r] → [i, st, val ' + mklist(initial_value(ty), i→n(i0)), ty, r] ]
