1) Show the set of R commands that would create the vector of character strings that represent the locations of the classes that you are taking this semester.(For any class meeting virtually, you can make up locations.)For example, the strings in your vector might be "Beury 124," "Carnell 101," "Alter 023," and "Klein 331." Assign the classname that meets there (e.g., "Math221") as the name for each position of the vector.

2) Show the expression using the vector you created in problem 1 that would display the meeting location for Math221, regardless of where Math221 is in your vector. Do not use a loop.

3) Show the expression that produces the vector of class codes in your schedule from #1 EXCEPT for Math221. Do not use a loop.
