A[5] and A[7], etc. Again, the work to be performed by each of these processors is what has been described earlier for the
block D since we are combining two blocks, with the difference that the new constant C should now be 22d mod P = C2.
The results will be stored right-justified in 4d-bit blocks, of which, as before, only the rightmost d bits or less will be
affected. Continuing with further steps will yield a single operation after log n iterations, and the final value B mod P will
be in A[n − 1].
