title: Trimming a string with <= 2 characters
body: <p>Suppose you are given an input string:</p>
  
  <pre><code>"my name is vikas"
  </code></pre>
  
  <p>Suggest an algorithm to modify it to:</p>
  
  <pre><code>"name vikas"
  </code></pre>
  
  <p>Which means remove words having length <code>&lt;=2</code> or say <code>k</code> characters, to make it generic.</p>
