title: Fastest way to remove first char in a String
body: <p>Say we have the following string </p>
  
  <pre><code>string data= "/temp string";
  </code></pre>
  
  <p>If we want to remove the first character <code>/</code> we can do by a lot of ways such as :</p>
  
  <pre><code>data.Remove(0,1);
  data.TrimStart('/');
  data.Substring(1);
  </code></pre>
  
  <p>But, really I don't know which one has the best algorithm and doing that faster..  <br/>
  <strong>Is there a one that is the best or all are the same ?</strong>  </p>
