Please answer as soon as possible

Consider the function doIt defined as follows:

def doIt(numbers: Array[Double], x: Double, y: Double) =
    numbers.filter( (number: Double) => number >= x - y && number <= x + y )

If numbers is:

numbers = Array(2.5, 1, 3.2, 9.3, 2, 9, 1.5)

What is returned by doIt(numbers, 2, 3)?

Homework Answers

Answer #1

It will return

2.5 1.0 3.2 2.0 1.5

because these numbers lies between range -1(=2-3) and 5 (=2+3)
