Proof step 10 from proof copy-append (previous step)

n = n0 + # ar0, # ar0 ≤ n, n + m1 ≤ # ar0 + # ar1 ⊦ copy(ar0 + ar1, n, ar2, m0, m1) = copy(ar1, n0, ar2, m0, m1)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
n0 + m1 ≤ # ar1 ⊦ copy(ar0 + ar1, n0 + # ar0, ar2, m0, m1) = copy(ar1, n0, ar2, m0, m1)
