Rewrite each of the following arithmetic expressions in (a-d) to take advantage of concurrent processing system with five available processors, and then use pseudocode to show the order of your calculations. Use the terms COBEGIN and COEND to delimit the concurrent sections. a. B * R + Y * Z – N * M + C2
b. B * (R + Y) * (Z – N) * M + C2
c. (A * (B * C) * (D * E) + F + G - H)
d. ((J + K * L * M * N) * I)
