Let x[n] = {−1, 0, 1, 2, 3,4, 4, 4, 4, 4}, for n=[-5 :4]

a. Determine the sequences x[−n], x[n − 3], and x[n + 2] by hand.

b. Build two functions fold (for reversing) and shift (for shifting the sequence) and use it to repeat the previous part.

c. Plot the sequences x[n], x[−n], x[n − 3], and x[n + 2] using the function stem on the same figure.
