Problem 1: Operations on sequences. (10 points) Consider the sequence x[n] = {1 0 -1 0 1 0}, -1 5ns 4, where the sample values outside the specified range are all zeros. And the sequence: y[n] = {-1 0 1 0 -1 0 1}, -3 5ns3, where the sample values outside the specified range are all zeros. Generate the sequence u[n] = -x[n 1] +y[-n + 2]
