Proof step 5 from proof getintarray-rec-first (previous step)

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)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
0 ≤ i0 ⊦ intvalues(getarray(r, i + 1, i0, st)) = getintarray(r, i + 1, i0, st)

Rule argument
