Hi Siddhartha,

Thank you for reporting this.

I've gone ahead and forwarded this report to the content team. In the future, the best way to report errors is directly on the page. This is the simplest and fastest way for the information to get directly to the people responsible for that part of the site.

This is how to do this:
1) Click the "Report a problem" link at the bottom of the exercise.
2) Select the option that describes the mistake that you found.

This feedback will go directly to the content team where it'll be reviewed.

Thanks again for helping us improve the site! If there's anything else you need, I'm happy to help. :)

All the best,

Le
