Proof step 40 from proof prepost-resize (previous step)

copy(kar, 0, mkkeyarray(n0), 0, m)[m0] = key-index(key, m1), 2exp-size(# kar), 2exp-size(n0), m0 < # kar, m0 < n0, m0 < minsize, m0 < m, m < n0, m < minsize, m0 + 1 < minsize, m0 + 1 < n0, heap-order(kar, m), no-dups-idx(kar, m), valid-idx(kar, ar, m), m ≤ # kar, minsize ≤ n0 ⊦ m1 < # ar ∧ ar[m1].idx = m0

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 41:
copy(kar, 0, mkkeyarray(n0), 0, m)[m0] = key-index(key, m1), ar[m1] = elemindex(a, m2), 2exp-size(n0), 2exp-size(# kar), m0 + 1 < n0, m0 + 1 < minsize, m < minsize, m < n0, m0 < m, m0 < minsize, m0 < n0, m0 < # kar, heap-order(kar, m), no-dups-idx(kar, m), valid-idx(kar, ar, m), minsize ≤ n0, m ≤ # kar ⊦ m1 < # ar ∧ m2 = m0

Rule argument

spec: elem-index name: elim seq: ⊦ a = ei.elem ∧ m = ei.idx ↔ ei = elemindex(a, m) subst: [ei, a, m] → [ar[m1], a, m2]

Additional information

Used simplifier rules: ⊦ a = ei.elem ∧ m = ei.idx ↔ ei = elemindex(a, m); (elim) Used terms: ar[m1], a, m2
