Proof step 31 from proof get-rest (previous step)

0 ≤ i0 ⊦ getarray(r, i, i0 + 1, st) .rest = getarray(r, i + 1, i0, st)

User applied rule induction

And obtained the following new goals

Proof step 30:
0 ≤ i0, ∀ i1, r, i, st. i→n(i1) < i→n(i0) → (0 ≤ i1 → getarray(r, i, i1 + 1, st) .rest = getarray(r, i + 1, i1, st)) ⊦ getarray(r, i, i0 + 1, st) .rest = getarray(r, i + 1, i0, st)

Rule argument

[INDHYPARG : [STANDARDINDUCTIONTYPE : ], true, false, i→n(i0), [] → [], <]
