wanted

使用 Java 爬取 LeetCode 题目内容以及提交的AC代码 传送门 Description We have a set of items: the i -th item has value values[i] and label labels[i] . Then, we choose a subset S of these items, such that: |S| <= num_wanted For every label L , the number of items in S with label L is <= use_limit . Return the largest possible sum of the subset S . Example 1: Input: values = [5,4,3,2,1], labels = [1,1,2,2,3], num_wanted = 3, use_limit = 1 Output: 9 Explanation: The subset chosen is the first, third, and fifth item. Example 2: Input: values = [5,4,3,2,1], labels = [1,3,3,3,2], num_wanted = 3, use_limit = 2 Output:

(actually, any implementations - R*, R+ or PR-tree would be great) It doesn't matter if it is a template or library implementation, but some implementations that Google found look very disappointing... 回答1: Check R-Trees code on http://www.superliminal.com/sources/sources.htm also check http://www.virtualroadside.com/blog/index.php/2008/10/04/r-tree-implementation-for-cpp/ 回答2: You may also check out the rtree variants provided by the Boost.Geometry
