A Kotlin Implementation of Bubble Sort :D (bubble sort is the starter "project" that I do when learning new langs)

bubbleSort.kt

fun main() {
  var arr = arrayOf(4, 1, 3, 7, 6, 5, 8, 2)
  println(arr.contentToString())
  for (i in 1..arr.size) {
    for (j in 0..arr.size-i-1) {
      if (arr[j] > arr[j+1]) {
        arr[j] = arr[j+1].also { arr[j+1] = arr[j] }
      }
      var outArr = arr.contentToString()
      println("iter $i.$j | $outArr")
    }
  }
}
