The sum of the squares of the first ten natural numbers is,
$1^2 + 2^2 + dots + 10^2 = 385$
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
$3025 − 385 = 2640$
For a given input n, find the difference between the sum of the squares of the first n natural numbers and the square of the sum.
Test cases
1 => 0
2 => 4
3 => 22
10 => 2640
24 => 85100
100 => 25164150
This challenge was first announced at Project Euler #6.
Winning Criteria
There are no rules about what should be the behavior with negative or zero input.
The shortest answer wins.

Pretty simple way of doing it with a couple of tricky shifts. Hopefully someone will find some more tricks to make this even shorter.

You shouldn't use anything but the value as input. What is that '-x' doing? It should be considered to measure the score.

It's a flag, we don't count them.

@EduardoHoefel It's a slightly strange quirk of the site that a language + flags is a language in it's own right by meta consensus (hence the title "Japt -x")

@EduardoHoefel That information is outdated. We don't count flags anymore.
