# Difference Of Squares

|
|

|
|
Welcome to Difference Of Squares on Exercism's C# Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.

## 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.
|
||
|
|
|
||
|
|
This exercise requires you to process a collection of data. You can simplify your code by using LINQ (Language Integrated Query).
