You can calculate your Body Mass Index (BMI) by dividing your weight by the square of your height. Here is an implementation of this function in Kotlin:
```fun bmi(weight: Double, height: Double): Double {
val heightM = height / 100.0
return weight / (heightM * heightM)
}
```

Write a program that asks for your weight and height, and outputs your BMI (using the above function).

Write a program that reads in a list of grades (integers, one per line) and then calculates the average of all the grades (double). The end of the list of grades will be the string "q". Start with the following template and write a function to calculate the average.
```fun main(args: Array) {
while (true) {
if (input == "q") {
// TODO call a function to calculate the average
println("Average is ?")
return
}
val num = input?.toIntOrNull()
if (num != null) {
Write a program that reads in a list of words (one per line) and then prints them all in reverse order. The program should contain the function `fun printReversed(list: List)`.
