WA3	Bogatyr	1797. Summit Online Judge. Version 2	27 Nov 2012 18:36	2
WA3 Bogatyr 27 Nov 2012 18:25 Interesting, most people hit WA2 then AC, but I skipped WA2 and jumped right to WA3, seem to be the first to hit it. Can't find the error....switched to java & BigInteger thinking numerical overflow in c++ may be the issue but still WA3. Argh.
