Proof step 19 from proof keyset-subarray-eq (previous step)

keyset(kar0, m0) = keyset(kar1, m0), subarray(kar0, 0, m0 + 1) = subarray(kar1, 0, m0 + 1), m0 < # kar1, m0 < # kar0 ⊦ keyset(kar1, m0) ++ kar0[m0] = keyset(kar1, m0) ++ kar1[m0]

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: array, inst: key-index-array name: Extension seq: ⊦ kar = kar0 ↔ # kar = # kar0 ∧ (∀ n. n < # kar → kar[n] = kar0[n]) subst: [kar0, kar] → [subarray(kar1, 0, m0 + 1), subarray(kar0, 0, m0 + 1)] flags: <all paths>
