Parking Fee Question in Kotlin course

Question

Okay, so as per the question, i have set the code and there are 6 test cases. 3 are passing while other 3 are failing 😂. Please someone help me and tell me what is the problem in my code ?

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
for(i in 1..hours){
if(i<=5){
total += 1.0
}else if(i>5 && i<24){
total += 0.5
}else{
total = 15.0 + (0.5*(hours-24))
break
}
}
println(total)
}

Thanks for help.

Answer 2

Parking Fee question answer is 👇

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
if (hours>=24) {
var days: Int = 0
days = hours/24
total = days*15+(hours-days*24)*0.5
}
else if (hours>5) {
total = 5+(hours-5)*0.5
}
else {
total = hours*1.0
}
println(total)
}

There maybe more than 48 hours so else condition will be like this:

total = 15 * (hours / 24) + 0.5 * (hours % 24)

Answer 4

Manmeet

There maybe more than 48 hours so we have to divide with 24 to get exact days and we have to use Modulus Operator (%) to get remaining hours.

So if there is 49 hours then 49 / 24 will give 2 days and for remaining 1 hour we have to use modulus operator.

So (49 / 24) = 2 days
and (49 % 24) = 1 hours

So according to 15$ / days = 2 * 15
According to 0.5$ /hours = 0.5 * 1

Answer 5

fun main(args: Array<String>) {
var hours = readLine()!!.toInt()
var total: Double = 0.0
when{
hours in 1..5 -> total = hours.toDouble()
hours in 6 until 24 -> total = (hours - 5)*0.5 + 5
hours >= 24 -> total = (hours/24).toDouble() *15 + (hours%24)*0.5
}
println(total)
}

Более изящно, без циклов и лишних переменных)

Answer 6

Bot isn't break statement breaking the loop on first iteration ?

Answer 7

Simba Thanks bro, I had searched for this answer but didnt get why they were dividing hours by 24. Thanks a lot again.

Answer 8

🅰🅹 🅐🅝🅐🅝🅣 Thanks bro

Answer 9

you are adding 15 plus additional charges of 0.5*(hours-24) on every iteration when the additional charge should be added only once

Answer 10

ah yes sorry didn't notice that, but then you didnt have $15 for every 24 hours, you only have $15 for first 24 hours

Answer 11

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

var prifix = when {
hours in 6..23 -> 5
hours >= 24 -> 15
else -> 0
}

val price: Double = when {
hours in 1..5 -> 1.0
hours in 6..23 -> 0.5
hours >= 24 -> 0.5
else -> 0.0
}

if (hours >= 24) {
prifix *= hours / 24
hours %= 24
total = prifix + (hours * price)
}
else if (hours in 6..23) {
hours -= 5
total = prifix + (hours * price)
}
else{
total = hours * price
}

println(total)

}
