hdu2602Bone Collector (简箪01背包)

Many years ago , in Teddy’s hometown there was a man who was called “Bone Collector”. This man like to collect varies of bones , such as dog’s , cow’s , also he went to the grave …
The bone collector had a big bag with a volume of V ,and along his trip of collecting there are a lot of bones , obviously , different bone has different value and different volume, now given the each bone’s value along his trip , can you calculate out the maximum of the total value the bone collector can get ?

The first line contain a integer T , the number of cases.
Followed by T cases , each case three lines , the first line contain two integer N , V, (N <= 1000 , V <= 1000 )representing the number of bones and the volume of his bag. And the second line contain N integers representing the value of each bone. The third line contain N integers representing the volume of each bone.

One integer per line representing the maximum of the total value (this number will be less than 2 ³¹).

题目意思：有T组，每组有三行，第一行有两个数n(骨头数)和包的总体积，第二行是每个骨头价值，第三行是每个骨头的占用体积。输出要求背包能装最大的价值。
