title: Compare two strings one shifted by a position
body: <p>I have theses two strings:</p>
  
  <pre><code>String s1 = "hello"; 
  String s2 ="_hello";
  </code></pre>
  
  <p>I wish to return <code>true</code> (the second string is shifted by a position) for such strings when I compare them. </p>
  
  <p>Which <code>String</code> manipulation method should I use? Can anyone give me a hint on this?</p>
