My program only returns the days of a non-leap year Kotlin
fun main(args: Array) {
val year = 2020
var leap = false
val month = 10
if (year % 4 == 0) {
if (year % 100 == 0) {
leap = year % 400 == 0
} else
leap = true
val numDay = when (month){
1 ->"31"
2 ->"29"
3 ->"31"
4 ->"30"
5 ->"31"
6 ->"30"
7 ->"31"
8 ->"31"
9 ->"30"
10 ->"31"
11 ->"30"
12 ->"31"
else ->"Invalid Argument"
}


I can't read the numDay of a leap...
