Please write your code in R and submit your script and results for each of the following , Note , Use R language.

7. Create key stream bit by XOR-in the appropriate bits from x, y, and z vectors. tr) # code goes here 8. Write a function for the above and create a 128 bit key stream with the seed mentioned in question 3. You function should contain two parameters: a seed and a key length. tr) # code goes here 9. Create an integer vector S with values from 1-5. Swap elements 1 and 4. Hint: use the swap0 function in package seqinr. Ir) # code goes here 7.
