Proof step 6 from proof getintarray-rec-first (previous step)

0 ≤ i0 ⊦ intvalues(getarray(r, i, i0 + 1, st)) = st[r -- i '] .intval ' + getintarray(r, i + 1, i0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ 0 < j → getarray(r, i, j, st) = st[r -- i '] ' + getarray(r, i + 1, j - 1, st)
Proof step 5:
0 < i0 + 1, 0 ≤ i0 ⊦ intvalues(st[r -- i '] ' + getarray(r, i + 1, i0 + 1 - 1, st)) = st[r -- i '] .intval ' + getintarray(r, i + 1, i0, st)

Rule argument

[crewrite-arg: get-rec-01, F, [st, j, i, r] → [st, i0 + 1, i, r]]
