//Sum square difference
//Problem 6
//The sum of the squares of the first ten natural numbers is,
//12 + 22 + ... + 102 = 385
//The square of the sum of the first ten natural numbers is,
//(1 + 2 + ... + 10)2 = 552 = 3025
//Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 âˆ’ 385 = 2640.
//Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.
