Please find my sample solution here:

for(num in 1..10000) {
    if(num == 9001)
        print("IT'S OVER 9000!!!")
}

As usual, there are many different solution for this :)

var humidity = "humid"
var humidityLevel = 80
while (humidity == "humid"){
    humidityLevel-=5
    println("humidity decreased")
    if(humidityLevel < 60){
        humidity = "comfy"
        println("it's comfy now")
    }
}
