Proof step 4 from proof putarray-add-same-01 (previous step)

⊦ putArray(vals, r, 0, addarray(r, initial_value(ty), n→i(# vals), st[r -- _type, typeval(mkarraytype(ty))][r -- _length, intval(n→i(# vals))])) = addarray(r, vals, 0, st[r -- _type, typeval(mkarraytype(ty))][r -- _length, intval(n→i(# vals))])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ i = n→i(# vals) ∧ val = initial_value(ty) → putArray(vals, r, 0, addarray(r, val, i, st)) = addarray(r, vals, 0, st)

Rule argument

[crewrite-arg: putarray-add-same-02 , F , [i, vals, val, ty, r, st] → [n→i(# vals), vals, initial_value(ty), ty, r, st[r -- _type, typeval(mkarraytype(ty))] [r -- _length, intval(n→i(# vals)) ]] ]
