title: How many times will "Hello World" be printed?
body: <pre><code>for (int i = 0; i &lt; n; i++)
      for(int j = 0; j &lt; i; j++)
          printf("Hello World");
  </code></pre>
  
  <p>I think the answer should be n(n)! because the outer loop executes n times and the inner loop (n)! times.</p>
