Proof step 14 from proof get-del-01 (previous step)

∀ j0, r, r0, i, st. i→n(j0) < i→n(j) → (true → r = r0 ∨ getarray(r, i, j0, st -- r0) = getarray(r, i, j0, st)) ⊦ getarray(r, i, j, st -- r0) = getarray(r, i, j, st), r = r0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ j ≤ 0 → getarray(r, i, j, st) = []
Proof step 12:
¬ j ≤ 0, ∀ j0, r, r0, i, st. i→n(j0) < i→n(j) → (true → r = r0 ∨ getarray(r, i, j0, st -- r0) = getarray(r, i, j0, st)) ⊦ getarray(r, i, j, st -- r0) = getarray(r, i, j, st), r = r0
Proof step 13:
⊦ j ≤ 0 → getarray(r, i, j, st) = []

Rule argument

[crewrite-arg: getArray-zero, F, [st, j, i, r] → [st -- r0, j, i, r]]
