Its tough to draw it here.)</p> <p>but I get:</p> <pre><code>** * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * </code></pre> <p>Look at the first line. It has first 2 "*"s together. As per the code it is not supposed to happen. Something is going wrong in the <code>document.write("*")</code> part. When I tried debugging using <code>alert</code> what I found out is that the first time (i.e when i=0) the first <code>document.write("*")</code> gets ignored. But every other time it is considered.</p>
