	// Thanks to the Internet Archive, I could get the "score table" HTML source without waiting for a real
	// contest. I just go to http://web.archive.org/web/*/https://codeforces.com/contest/*, then filter by
	// 'contest/' and sort by unique.
	// The page with the maximum unique count must have the score table.
	//
	// Taken from page: http://web.archive.org/web/20151230151115/http://codeforces.com/contest/611
	// (or http://web.archive.org/web/20160123153752/http://codeforces.com/contest/617 for Russian version)
	//
	// Currently only English is supported, but it's trivial to add the Russian version.
