1) Polynomial P is represented by coefficients: co = [1, 2, 0, 3].  Polynomial Q is represented by coefficients: co2 = [1, -4]

Polynomial R = P + Q

Appropriately initialize the coefficients for R by initializing the array 'sum'.

Polynomial S = P*Q

Appropriately initialize the coefficients for S by initializing the array 'prod'.
