Display a string in reverse by using recursion
 

using System; 
  
class RevStr 
 
  // Display a string backwards. 
  public void displayRev(string str) { 
    if(str.Length > 0)  
      displayRev(str.Substring(1, str.Length-1))
    else  
      return
 
    Console.Write(str[0])
  

 
public class RevStrDemo 
  public static void Main() {   
    string s = "this is a test"
    RevStr rsOb = new RevStr()
 
    Console.WriteLine("Original string: " + s)
 
    Console.Write("Reversed string: ")
    rsOb.displayRev(s)
 
    Console.WriteLine()
  
}
