A research student is given a singly-linked list. Each node
of the list has a color, which is either “Black”
or “White”. He must find if there are more black nodes than
white nodes, or vice versa. His advisor
gives him 5,000Rs to buy a computer to do the work. He goes
to the computer store and finds a
slightly defective computer which costs a mere 3,000Rs. This
computer has the small problem of not
being able to do arithmetic. This means that he cannot use a
counter to count the nodes in the list to
determine the majority color. The computer is otherwise
fully functional. He has the evil idea that he
could buy the defective computer and somehow use it to do
his work, so that he can use the rest of
the money on enjoyment. Show how he can accomplish this
amazing task. Write code for an algorithm
called ‘findMajorityColor’ which takes a singly-linked list,
L, with n nodes and returns the majority color
among nodes of L. This algorithm should have the same
asymptotic running time as counting the
nodes (O(n)). Note: No arithmetic is allowed.

Implement a command console for changing settings on a particular object. The command console should allow you to enter a string and will return the response (very similar to a terminal session). The commands are as follows: SET propertyname=newvalue will change the target object’s member named “propertyname” to have a value equal to “newvalue”. If the input value is incompatible (i.e. an int being set to a string), print out an appropriate error message. GET propertyname will print out the current value of the target object’s member named “propertyname”. GET * will print out a list of all target object members and their current values. The system should be extensible for future commands and should accept an arbitrary object, such that another developer could insert another object into the system and rely on the command console to get and set the properties correctly.
