title: What is the complexity of empty for loop?
body: <p>I was wondering if the complexity of a empty for loop like below is still <strong>O(n^2)</strong></p>
  
  <pre><code>for (int i = 0; i &lt; n; i++) {
      for (int j = 0; j &lt; n; j++) {
      }
  }
  </code></pre>
  
  <p>update : changed height and width variable to n</p>
