Provides translations in Romanian, Russian, Korean and German for Project Euler problems
Pada tanggal
This script is for the mathematical problems site Project Euler.
It places 5 flags (British, Romanian, Russian, Korean and German) on top of every problem's page. By clicking on the flag, the corresponding translation of a problem is retrieved.
Obviously, not at all problems are available in the above mentioned languages. In this case, clicking on the flag will do nothing.
You can see a demo on how the script works in the video on this page: http://projecteuler.javafling.org/greasemonkey.php
