Proof step 7:
getbytearray(r, i0, i - i0, st) + getbytearray(r, i, j0 + i0 - i, st) = getbytearray(r0, i0, i - i0, st0) + getbytearray(r0, i, j0 + i0 - i, st0), i ≤ i0 + j0, i0 ≤ i, 0 ≤ j0, i + j ≤ i0 + j0 ⊦ # getbytearray(r, i0, i - i0, st) = # getbytearray(r0, i0, i - i0, st0), getbytearray(r, i, j, st) = getbytearray(r0, i, j, st0)
