Proof step 15 from proof putByteArray-put-switch (conclusion)

⊦ 0 ≤ j ∧ 0 ≤ i ∧ j < i → putByteArray(bytes, r, i, st[r -- j ', byteval(by)]) = (putByteArray(bytes, r, i, st)[r -- j ', byteval(by)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 14:
j < i, 0 ≤ j, 0 ≤ i, 0 < i ⊦ putByteArray(bytes, r, i, st[r -- j ', byteval(by)]) = (putByteArray(bytes, r, i, st)[r -- j ', byteval(by)])

Rule argument
