Proof step 26 from proof putBar-rew (previous step)

j < i ∨ i + n→i(# bytes) ≤ j ⊦ r0 -- sk = r -- j ', (putByteArray(bytes, r, i, st)[r0 -- sk]) = (putByteArray(bytes, r, i, st[r -- j ', val])[r0 -- sk])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
⊦ r ≠ r0 → (putByteArray(bytes, r, j, st)[r0 -- sk]) = st[r0 -- sk]
Proof step 25:
j < i ∨ i + n→i(# bytes) ≤ j ⊦ sk = j ', (putByteArray(bytes, r, i, st)[r -- sk]) = (putByteArray(bytes, r, i, st[r -- j ', val])[r -- sk])

Rule argument
