CodeChefMonkey is a userscript that inserts the link of a practice problem in the page of the related contest problem. The link is inserted in the bottom panel, the same that has links to the editorial and author. The link is built according to the instructions of this post.
- Install the Chrome Extension Tampermonkey, or equivalent for other browsers.
- Click here and install. Alternatively, copy and paste the content of CodeChefMonkey.user.js in Tampermonkey.
Sometimes the link is not inserted. In this case, try to reload the page. I don't know the root cause of this behavior but feel free to submit a pull request if you figure it out.
