Hi everyone,
Here's a tool to help classify SPOJ's problems
http://vnoi.info/index.php?option=com_voj&task=classify&site=spoj24
It's a tagging system and it works as follows:
There's several predefined tags like "Dynamic programming", "Greedy", "Ad hoc", etc. If you think a problem related to a tag, you can attach this tag to the problem.
You can filter problems related to a specific tag by using the filter link at the top of the page.
If a problem is not in the list yet, you can add it to the list by using the "Add a problem" box at the bottom of the page.
When you finished solving a problem in SPOJ, you can help other users classify this problem by attach some tags to it.
Thanks.
