'''The sum of the squares of the first ten natural numbers is,
(1)^2 + (2)^2 + ... + (10)^2 = 385
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.
