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")

    }

}
