Back in our project, let’s implement the algorithm we just designed to calculate the difference between the slider and the target value in Swift.

if something is true {
  then do this
} 
} else if something else is true {
  then do that instead
}
} else {
  do something when neither of the above are true
}
func points(sliderValue: Int) -> Int {
  var difference: Int
  if sliderValue > target {
    difference = sliderValue - target
  } 
  } else if target > sliderValue {
    difference = target - sliderValue
  } 
  } else {
    difference = 0
  }
  var awardedPoints: Int = 100 - difference
  return awardedPoints
}
