Question $6$: Integer and Logical Vector Subsetting

The following code creates a numeric vector named vec which has length $100.$

Create four new vectors:

positive: A numeric vector that contains the elements of vec at indexes $3,12,$ and $32.$

negative: A numeric vector that contains all of the elements of vec, except for those at indexes $9,17,$ and $32.$

even: A numeric vector that contains the elements of vec at even indexes.

large: A numeric vector that contains all of the elements of vec that are greater than $66$
