Proof step 12 from proof copy-other-weak (previous step)

m + n2 < n1 + m0, m + n2 < # ar, n2 < # ar0, n1 < # ar1, n1 < n0, # ar ≤ n1 + m0, m0 + n0 ≤ m, n0 ≤ # ar1, ∀ n1, n0, ar1, ar0, m, ar, m0. n1 < n0 ∧ n1 < # ar1 ∧ n2 ≤ # ar0 ∧ n0 ≤ # ar1 ∧ m + n2 ≤ # ar ∧ m0 + n0 ≤ m ∧ # ar ≤ n1 + m0 ∧ m + n2 ≤ n1 + m0 → copy(ar0, 0, ar, m, n2)[n1 + m0] = ar[n1 + m0] ⊦ copy(ar0, 0, ar, m, n2)[n1 + m0] = ar[n1 + m0]
