USING R

Store the following binary number as a character string s: 111000.

Convert this into a character vector v.

Expand the character vector v to 8 bits as follows: swap v[3] and v[4] .

Replicate v[3] and v[4] . The result (call it ev) should be a character vector of size 8.

Write a function called expand() that takes a binary vector of size 6 as input and returns a binary vector of size 8 as output.
