Proof step 22 from proof get-rec-01 (conclusion)

⊦ 0 < j → getarray(r, i, j, st) = st[r -- i '] ' + getarray(r, i + 1, j - 1, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 21:
0 < j ⊦ getarray(r, i, j, st) = st[r -- i '] ' + getarray(r, i + 1, j - 1, st)
