#Questions
** Questions should be answered with the simplest, most barebone solution possible.
###1. Arrays
array = ["Blake","Ashley","Jeff"]
a. Add a element to an array
b. Write a statement to print out all the elements of the array.
c. Return the value at index 1.
d. Return the index for the value "Jeff".
###2. Hashes
`instructor = {:name=>"Ashley", :age=27}`
a. Add a new key for location and give it the value "NYC".
b. Write a statement to print out all the key/value pairs in the hash
c. Return the name value from the hash.
d. Return the key name for the value 27.
###3. Nested Structures
```ruby

:subject=>"karaoke"}]
:students => [ {:name => "Marissa",
:grade => "B"},
{:name=>"Billy",
:grade => "F"},
{:name => "Frank",
:grade => "A"},
{:name => "Sophie",
:grade => "C"}
]
}
```

###4. Methods
**Note: You will need to pass the school variable to each of these methods to include it in scope.
a.
i. Create a method to return the grade of a student, given that student's name.
ii. Then use it to refactor your work in 3.i.
b.
i.Create a method to udpate a instructor's subject given the instructor and the new subject.
ii. Then use it to update Blake's subject to "being terrible".
c.
i. Create a method to add a new student to the schools student array.
ii. Then use it to add yourself to the school students array.
d.
i. Create a method that adds a new key at the top level of the school hash, given a key and a value.
ii. Then use it to add a "Ranking" key with the value 1.
#5. Object Orientation
a. Create a bare bones class definition for a School class.
b. Define an initialize method for the School class.
i. Give your School class the instance variables: name, location, ranking, students, instructors.
**NOTE: These variables should be of the same type as they are in the hash above.
ii. Rewrite your initialize method definition to take a parameter for each instance variable.
iii. Initialize each instance variable with the value of the corresponding parameter.
c. Create an attr_accessor for name, location, instructors, and students. Create an attr_reader for ranking.
d. Create a method to set ranking, given a ranking value.
e. Create a method to add a student to the school, given a name, a grade, and a semester.
f. Create a method to remove a student from the school, given a name.
