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)
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 (sliderToInt > targetValue) {
    difference = sliderToInt - targetValue
} else if(targetValue > sliderToInt) {
    difference = targetValue - sliderToInt
} else {
    difference = 0
return maxScore - difference
