$($d$)$ D $=[1,-1,1,-1,1,-1,...]$ up to n $=10$ terms. Modify your code to work for n $=100.$

$($e$)$ E $=[0,1/2,2/3,3/4,4/5,5/6,...]$ up to n $=10$ terms. Modify your code to work for n $=100.$

HINT: Create a ten element vector such as A$=1$:$10($or A$=1$:$100),$ and then use a loop for $10($or

$100)$ iterations to change each value in the vector A using a formula involving the loop variable.
