Solution for Problem 6 of Project Euler
https://projecteuler.net/problem=6
=#
function Problem6()
#=
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. Statement
=#
n = 100
square_of_sum = sum(i for i in (1:n))^2
sum_squares = sum(i^2 for i in 1:n)
diff = square_of_sum - sum_squares
return diff
