# Difference Of Squares
Find the difference between the sum of the squares and the square of the sums of the first N natural numbers.
The square of the sum of the first ten natural numbers is,
(1 + 2 + ... + 10)**2 = 55**2 = 3025
The sum of the squares of the first ten natural numbers is,
1**2 + 2**2 + ... + 10**2 = 385
Hence the difference between the square of the sum of the firstten natural numbers and the sum of the squares is 2640:
3025 - 385 = 2640
To run the tests simply run the command `go test` in the exercise directory.
If the test suite contains benchmarks, you can run these with the `-bench`flag:
go test -bench .
