切木料(DP)问题 | Hello World

有一个长为L的木料需要割开,切的位置在一个数组里A[0…N],从一个地方切开的
cost是当前所切木料的长度。按不同的顺序切割,得到的total cost是不一样的,问怎
么切cost最
小。

我对题意的理解是,比如一个木料现在10米长,然后切的位置是2米处,4米处和7米处
(就是说arr A里A[0]是2,A[1]是4, A[2]是7)。那么比如先切2米,那么得到cost是
10(因为现在木料长度为10),然后切4米处,那么cost变成10 + 8(因为8是现在切的
时候木料的长度)。然后切7米处,cost变成10 + 8 + 6。那么这种切法总共的cost是24。
