#3896 F-Where is the pig

Demult într-o vreme îndepărtată trăiau Foarte mulți porci. Pentru că erau atât de mulți trebuia să le fie construite anumite țarcuri reprezentate prin poligoane nu neapărat convexe. Din cauza unui antrenament militar cu focuri de armă mai mulți porci riscau să moară.

Se dau N poligoane nu nepărat convexe reprezentând țarcurile porcilor, toate complet în cadranul 1. Fiecare poligon are un cost atașat reprezentând numărul de porci din acel țarc. Se mai dă K și K perechi de coordonate X_i Y_i cu semnificația că la a i-a tragere traiectoria glonțului fi o semidreaptă care va porni din (0, 0) și va face un drum infinit de mare care va trece și prin (X_i, Y_i). Dacă la o tragere glonțul va lovi unul dintre țarcurile porcilor atunci din acel țarc vor muri toți porcii iar glonțul își va continua normal traiectoria. Pentru fiecare tragere trebuie să spuneți care este numărul de porci omorâți dacă am face doar acea tragere.
