Proof step 24 from proof cut (previous step)

# ar = m + 1, n ≤ m ⊦ ar[n] = copy(ar, 1, mkarray(m + 1), 1, m)[0, ar[0]][n], ar = []

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: array name: Put-other seq: ⊦ m ≠ n → ar[n, a][m] = ar[m] subst: [m, a, n, ar] → [n, ar[0], 0, copy(ar, 1, mkarray(m + 1), 1, m)] flags: <all paths>

Additional information

Used simplifier rules: ⊦ # copy(ar, m, ar0, m0, n) = # ar0; (s)% ⊦ # mkarray(n) = n; (s)% ⊦ 0 < m ↔ m ≠ 0; (s)% ⊦ m + 1 ≠ 0; (s)%a: ⊦ (m + n0) + n1 = m + n0 + n1; from specification nat-basic%c: ⊦ m + n = n + m; from specification nat-basic%m < # ar ⊦ ar[m, a][m] = a; (s) Used terms: n, ar[0], 0, copy(ar, 1, mkarray(m + 1), 1, m)
