//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.
