Reverse string using recursion in kotlin

Kotlin program for Reverse string using recursion. Here problem description and explanation.

// Reverse string using recursion in Kotlin
class ReverseString
{
	// This is reversing the string elements recursively
	fun reverseText(text: String, location: Int): String
	{
		// Base condition to stop the recursion process
		if (location >= 0)
		{
			// Recursive function call
			return text.get(location).toString() +
              this.reverseText(text, location - 1);
		}
		// When no character remaining
		return "";
	}
	// This is handling the request process of reverse string elements
	fun reverse(text: String): String
	{
		// Display given string elements
		println("Before Text : [" + text + "]");
		return this.reverseText(text, text.length - 1);
	}
}
fun main(args: Array < String > ): Unit
{
	val task: ReverseString = ReverseString();
	var text: String = "ABCDE";
	text = task.reverse(text);
	// After reverse	
	println("After Text  : [" + text + "]\n");
	text = task.reverse("654A321");
	// After reverse	
	println("After Text  : [" + text + "]\n");
}

Output

Before Text : [ABCDE]
After Text  : [EDCBA]

Before Text : [654A321]
After Text  : [123A456]
