Proof step 4 from proof getintarray-rec-first (previous step)

0 ≤ i0 ⊦ intvalues(getarray(r, i + 1, i0, st)) = getintarray(r, i + 1, i0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ getintarray(r, i, j, st) = intvalues(getarray(r, i, j, st))

Rule argument

[crewrite-arg: getintarray, F, [st, j, i, r] → [st, i0, i + 1, r]]
