Intermediate Assignments

1. Write a function that returns the most common item in an array of only numbers.

2. Write a function that returns the most common item in an array of strings or numbers.

3. Make a Car class with gas field and prototype method "go" which prints "vroom vroom!" if you have gas left, reducing gas by 1. Otherwise it will print "Out of gas :(". Make a "refill" prototype method that takes in an integer of gas to refill, and adds that to your gas.

4. Make a LinkedList prototype class. This should include methods to add, delete at index, insert at index, and get at index. A linkedlist is a structure with nodes that have a reference to the next node in the list. Look up the concept.

5. Make an ArrayList prototype class. This should include methods to add, delete at index, insert at index, and get at index. An ArrayList is a structure with a resizing array that holds the values for the list. Look up the concept.

6. Modify the LinkedList to be double-linked, having each Node have a pointer to the previous item also.

7. The eating Spaghetti problem. You're going to set up a table with 5 thinkers at it. The thinkers each can eat spaghetti. When they eat spaghetti they will eat it for 10milliseconds. They can only eat spaghetti if the two forks in front of them are unoccupied. After eating, they must think for 20 milliseconds. Stop after everyone has eaten 100 times. We're going to have each one on their own thread, using setTimeout with 0 milliseconds to repeatedly call its own logic.
