Discussion on: Project Euler #6 - Sum Square Difference

[Carlos E. Barboza]

Swift:

func sumSquareDifference(range: Int) -> Int {
    var sumOfSquares = 0
    var squareOfSum = 0
    for number in 1..<range+1 { //Is there a better way? Other than range+1?
        sumOfSquares += (number*number)
        squareOfSum += number
    }
    squareOfSum = squareOfSum*squareOfSum
    return (squareOfSum - sumOfSquares)
}

print(sumSquareDifference(range:100))
