• Introduction to Kotlin
• Data types
• Control Flow
• Functions
• Extension

All tasks will be solved in the Kotlin Playground.

1. Write a Kotlin application that displays your name.
2. Write a Kotlin function that computes the factorial for n in an iterative way (without recursion).
3. Modify the previous function in such a way that is is written as a single expression.
4. Write an operator extension to so that the !n will compute n the factorial of n. (Hint: Operator Overloading)
5. Write an Int extension function that computes (as Double) the logarithm of its parameter in base this. Use it in two ways:
   1. 2.log(8.0)
   2. 2 log 8.0
6. Modify the previous task to be able to use the function with Int numbers as well (`2 log 8`)
7. Make the following example work:

data class Complex (var r: Double, var i: Double)
 
fun main () {
    val a = Complex (1.0,2.0)
    val b = Complex (3.0,4.0)
 
    var s1 = a + b
    var s2 = a - b
    var s3 = a * b
    var s4 = a == b
    println (s1)
    println (s2)
    println (s3)
    println (s4)
}
