Need hint on where my code is going wrong (Parking fee task, Kotlin)

Question

This code passes 3 test cases but fails 3 (all hidden ones) and I can’t figure out why. I’ve manually tested many numbers in Kotlin playground and they all work. If anyone can hint what is causing the issue, I’d appreciate it!

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

total = when{
hours in 0..5 -> hours.toDouble()
hours in 6..23 -> (hours.toDouble()-5)*0.5+5
else -> (hours.toDouble()-24)*0.5+15
}
println(total)
}

Answer 1

The logic in your statements works for „up to a value“ only. Did you think, what hapen if the input value is much biger?

Answer 2

It is mentioned
- for ***each*** 24 hours, there is a flat fee of $15.

Your code only works till input is 47 hrs

Answer 3

Ah, thank you both! Completely forgot that multiple days exist *facepalm*
