	 * The square of the sum of the first ten natural numbers is,
	 * 		(1 + 2 + ... + 10)^2 = 55^2 = 3025
	 * 
	 * Hence the difference between the sum of the squares of the first ten natural numbers 
	 * and the square of the sum is 3025  385 = 2640.
	 * 
	 * Find the difference between the sum of the squares of the first one hundred natural numbers
	 *  and the square of the sum.
