ABC_FDTD_Die(T) Implements simulation of a Gaussian Pulse
over T time steps. ABC are for free space. If boundaries are in
the Dielectric medium then the ABC fail. Dielectric medium begin and
end can be specified with the code

一個(gè)簡(jiǎn)化的背包問(wèn)題：一個(gè)背包能裝總重量為 T，現(xiàn)有 n 個(gè)物件，其重量分別為（W1、W2、…、Wn）。問(wèn)能否從這 n 個(gè)物件中挑選若干個(gè)物件放入背包中，使其總重量正好為 T ？若有解則給出全部解，否則輸出無(wú)解。
