(5 points) Consider the following binary operations. For each operation, determine if the parallel prefix algorithm can be used to compute prefix sums of a sequence of n operands based on the given binary operation.
(a) op(a, b) = 2a + b
(b) op(a, b) = ab – (a + b)
(c) op(a, b) = Va2 + 62
(d) opla, b) = a × b (x is the vector cross-product in 3D) (Hint: For every ī, ã xã = 0, and axõ=0
