HDU 2602 Bone Collector(01背包)

Bone Collector Time Limit: 2000/1000 MS (Java/Others)    Memory Limit: 32768/32768 K (Java/Others) Total Submission(s): 44243    Accepted Submission(s): 18434     Problem Description 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 ?         Input 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.     Output One integer per line representing the maximum of the total value (this number will be less than 231).     Sample Input 1 5 10 1 2 3 4 5 5 4 3 2 1     Sample Output 14     Author Teddy     Source HDU 1st “Vegetable-Birds Cup” Programming Open Contest
