//Problem Statement
//
//You work for a company that sells mechanical bit counting devices.
These devices
//wear out when they do a lot of counting. You are going to see how
much wear has
//been put on one particular 15-bit binary counter. One unit of wear
occurs for
//every bit that is flipped in the counter.
//
//For example:
//If the counter was at 7 = 000000000000111
//And it was incremented to 8 = 000000000001000
//
//Then 4 bits are flipped so 4 units of wear would occur. If a counter
was
//incremented through an inclusive range like 7 -> 12 then :
//Starts at 7 = 000000000000111
//Goes to 8 = 000000000001000 7 -> 8 = 4 units of wear
//Goes to 9 = 000000000001001 8 -> 9 = 1 unit of wear
//Goes to 10 = 000000000001010 9 -> 10 = 2 units of wear
//Goes to 11 = 000000000001011 10 -> 11 = 1 unit of wear
//Goes to 12 = 000000000001100 11 -> 12 = 3 units of wear
//This causes a total of 4+1+2+1+3 = 11 units of wear. Return the total
wear caused by incrementing the counter through the inclusive range
between start and finish.
//Definition
//
//Class: MechanicalCounter
//Method: amountWear
//Parameters: int, int
//Returns: int
//Method signature: int amountWear(int start, int finish)
//
//(be sure your method is public)
//
//
//Constraints
//-start will be less than finish.
//-start will be between 0 and 32766 inclusive.
//-finish will be between 1 and 32767 inclusive.
//
//Examples
//0)
//7
//8
//Returns: 4
//As seen above, 4 units of wear occur when 7 becomes 8.
//
//1)
//
//7
//12
//Returns: 11
//The example in the problem statement.
//
//2)
//1
//32767
//Returns: 65518
