Selection sort in kotlin

Kotlin program for Selection sort. Here mentioned other language solution.

/*
  Kotlin program for selection sort
*/
class MySort
{
	// Swap the array element
	fun swap(arr: Array < Int > , x: Int, y: Int): Unit
	{
		// x and y are index of array
		val temp: Int = arr[x];
		arr[x] = arr[y];
		arr[y] = temp;
	}
	fun selectionSort(arr: Array < Int > , n: Int): Unit
	{
		var min: Int ;
		var i: Int = 0;
		// Execute loop from 0..n
		while (i < n)
		{
			// Get current index
			min = i;
			var j: Int = i + 1;
			while (j < n)
			{
				if (arr[min] > arr[j])
				{
					// Get the minimum element index
					min = j;
				}
				j += 1;
			}
			if (i != min)
			{
				// Swap minimum element at i index
				this.swap(arr, i, min);
			}
			i += 1;
		}
	}
	// Display array elements
	fun display(arr: Array < Int > , n: Int): Unit
	{
		var i: Int = 0;
		while (i < n)
		{
			// Display element value
			print("  " + arr[i]);
			i += 1;
		}
		print("\n");
	}
}
fun main(args: Array < String > ): Unit
{
	val task: MySort = MySort();
	// Array of integer elements
	val arr: Array < Int > = arrayOf(
      8, 2, 3, 8, 1, 3, 73, 121, 54, 23, 84, 13, 67, 23, 52);
	// Get the size of array
	val n: Int = arr.count();
	println(" Before Sort :");
	task.display(arr, n);
	// Test
	task.selectionSort(arr, n);
	println(" After Sort :");
	task.display(arr, n);
}

Output

 Before Sort :
  8  2  3  8  1  3  73  121  54  23  84  13  67  23  52
 After Sort :
  1  2  3  3  8  8  13  23  23  52  54  67  73  84  121
