Lets implement the algorithm we just designed to calculate the difference between the target value and the slider value in kotlin.

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
}
val maxScore = 100
var difference: Int
if (sliderValue > targetValue) {
    difference = sliderValue - targetValue
} else if(targetValue > sliderValue) {
    difference = targetValue - sliderValue
} else {
    difference = 0
}
return maxScore - difference
