title: Time Complexity of multiple nested loops
body: <p>What would be the complexity of the below code :
  Since the increment is not by 1 and the conditions are not direct, how to calculate the complexity ?</p>
  <pre><code>for(int h =0; h&lt;n;h+=2)
      {
         for (int j =1; j&lt;=n*n; j*=3)
         {
            for (int k =2; k+k &lt;=n;++k)
            { 
            } 
         } 
      }
  </code></pre>
