Question

I\'m a pretty experienced frontend engineer with a weak CS background. I\'m trying to get my head around the concept of recursion. Most of the examples and purported explana

Answer 1

This is a pretty straightforward C# implementation of the algorithm you asked for. I think it could be rewritten in javascript pretty easily.

// 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(); 
  } 
}
