title: Reverse elements of a string array
body: <p><code>string[] myString = {"a","b","c","d"}</code>
  <br/>
  <code>//Reverse string algorithm here</code>
  <br/>
  <code>myString = {"d","c","b","a"}</code>
  <br/>
  I have been asked to do so in an interview without the help of any temporary variable or .NET class, string methods, etc to reverse the elements of the same string array. I was told to use basic programming constructs like loops. Since, I am up for another interview today, I am in a hurry to know whether this is actually possible because I could not find a solution to this.</p>
