вернуться в форумwa 22 and then mysteriously AC: don't know why? when trying to update from (ux,uy) to (vx,vy) i was checking if (vx,vy) was already popped from priority_queue. this got me wa 22 many times. later, just out of frustation i removed the check and let (vx,vy) be updated even after it was once popped. and u know what, mysteriously got AC. of course, there has to be some logical explanation behind that. please explain anyone? Thanks in advance. Re: wa 22 and then mysteriously AC: don't know why? Послано shad 2 янв 2012 22:16 I followed by your advice, and also suprised! |
