Welcome to Difference of Squares on Exercism's C Track.

## Instructions
|
||
|
|
|
||
|
|
Find the difference between the square of the sum and the sum of the squares of the first N natural numbers.
|
||
|
|
|
||
|
|
The square of the sum of the first ten natural numbers is
|
||
|
|
(1 + 2 + ... + 10)² = 55² = 3025.
|
||
|
|
|
||
|
|
The sum of the squares of the first ten natural numbers is
|
||
|
|
1² + 2² + ... + 10² = 385.
|
||
|
|
|
||
|
|
Hence the difference between the square of the sum of the first ten natural numbers and the sum of the squares of the first ten natural numbers is 3025 - 385 = 2640.

You are not expected to discover an efficient solution to this yourself from first principles; research is allowed, indeed, encouraged.
|
||
|
|
Finding the best algorithm for the problem is a key skill in software engineering.
