Help with parking fee (kotlin)

Question

I am having issues trying to solve the parking fee question here is what I attempted to do

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
var one = 1.0
var pointfifty = 0.5

if (hours < 5){

hours = hours
println(hours)
}

else if (hours > 5){

var totals = hours / 1

total =(one * 5) + (totals * pointfifty )
println(total)

}

}

Any help is appreciated

Answer 1

(1) The output is always Double, but in the if statement you print an int.

(2) You didn't implement the parking fee which is 24 hours per $15.

(3) You else algorithm is wrong, if hours > 5, it will be 5 from the first 5 hours plus the rest of hours in a day multiplied by 0.5.

Answer 2

This is mine. I hope this can help you

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
var day : Int = hours/24
var addhours : Int = hours%24
total = when {
hours >5 && hours <24 -> 5.0+(hours-5)*0.5
hours >= 24 -> (addhours*0.5) + (day*15)
else -> hours*1.0
}
println(total)
}

Answer 3

I tired several logics write the function in an unbuggy way...
this is what I have written and it worked perfectly!!

var hours = readLine()!!.toInt()
var r = (hours / 24).toInt()
var total: Double = 0.0
if(hours >= 24){
hours = hours - (r*24)
total = total+(r*15)
if(hours >=0){
total = total+(0.5*hours)
}
}
else if(hours > 5 && hours < 24){
hours -= 5
total += 5
total = total+(0.5*hours)
}else{
total = hours * 1.0
}
println(total)

Answer 4

I tried the following on the IDE, it gives the correct results, but here on Sololearn ...although it says something like:

Output: 11.5
Expected: 11.5
🤦

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0

total = when {
hours == 24 -> 15 * 1.0
hours > 5 && hours < 24 -> 5 + (hours - 5) * 0.5
else -> hours * 1
}

println(total)
}

Answer 5

This works
fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var changed: Double = hours + 0.0
var total: Double = 0.0
var days: Int = hours/24
when {
changed <= 5.0 -> total = changed * 1.0
changed >= 5.0 && changed <= 24.0 -> total = (changed - 5.0) * 0.5 + 5.0
changed >= 24.0 -> total = 15 * days + (hours %24) * 0.5
}
println(total)
}
