Proof step 3 from proof replay-log-at-other (previous step)

n < # lpt ⊦ lpt.mapIndices(elems nx, λ lp. mklp(lp.ref-size, LEB_SIZE, LP_GROUP_NODES, lp.gcheapidx))[n] = lpt[n], n ∈ nx

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ lpt.mapIndices(ns, lptfun)[n] = (n ∈ ns ∧ n < # lpt ⊃ lptfun(lpt[n]);lpt[n])

Rule argument

spec: array-indices, inst: lp-array name: mapindices-at seq: ⊦ lpt.mapIndices(ns, lptfun)[n] = (n ∈ ns ∧ n < # lpt ⊃ lptfun(lpt[n]);lpt[n]) subst: [n, lptfun, ns, lpt] → [n, λ lp. mklp(lp.ref-size, LEB_SIZE, LP_GROUP_NODES, lp.gcheapidx), elems nx, lpt] flags: <all paths>

Additional information

Used simplifier rules: ⊦ n ∈ elems nx ↔ n ∈ nx; (s) Used terms: n, λ lp. mklp(lp.ref-size, LEB_SIZE, LP_GROUP_NODES, lp.gcheapidx), elems nx, lpt
