There is a set of n
items. You are given two integer arrays values
and labels
where the value and the label of the ith
element are values[i]
and labels[i]
respectively. You are also given two integers numWanted
and useLimit
.
Choose a subset s
of the n
elements such that:
s
is less than or equal to numWanted
.useLimit
items with the same label in s
.The score of a subset is the sum of the values in the subset.
\n\nReturn the maximum score of a subset s
.
\n
Example 1:
\n\n\nInput: values = [5,4,3,2,1], labels = [1,1,2,2,3], numWanted = 3, useLimit = 1\nOutput: 9\nExplanation: The subset chosen is the first, third, and fifth items.\n\n\n
Example 2:
\n\n\nInput: values = [5,4,3,2,1], labels = [1,3,3,3,2], numWanted = 3, useLimit = 2\nOutput: 12\nExplanation: The subset chosen is the first, second, and third items.\n\n\n
Example 3:
\n\n\nInput: values = [9,8,8,7,6], labels = [0,0,0,1,1], numWanted = 3, useLimit = 1\nOutput: 16\nExplanation: The subset chosen is the first and fourth items.\n\n\n
\n
Constraints:
\n\nn == values.length == labels.length
1 <= n <= 2 * 104
0 <= values[i], labels[i] <= 2 * 104
1 <= numWanted, useLimit <= n
我们有一个 n
项的集合。给出两个整数数组 values
和 labels
,第 i
个元素的值和标签分别是 values[i]
和 labels[i]
。还会给出两个整数 numWanted
和 useLimit
。
从 n
个元素中选择一个子集 s
:
s
的大小 小于或等于 numWanted
。s
中 最多 有相同标签的 useLimit
项。一个子集的 分数 是该子集的值之和。
\n\n返回子集 s
的最大 分数 。

示例 1:
\n\n\n输入:values = [5,4,3,2,1], labels = [1,1,2,2,3], numWanted = 3, useLimit = 1\n输出:9\n解释:选出的子集是第一项,第三项和第五项。\n\n\n
示例 2:
\n\n\n输入:values = [5,4,3,2,1], labels = [1,3,3,3,2], numWanted = 3, useLimit = 2\n输出:12\n解释:选出的子集是第一项,第二项和第三项。\n\n\n
示例 3:
\n\n\n输入:values = [9,8,8,7,6], labels = [0,0,0,1,1], numWanted = 3, useLimit = 1\n输出:16\n解释:选出的子集是第一项和第四项。\n\n\n

提示:
\n\nn == values.length == labels.length
1 <= n <= 2 * 104
0 <= values[i], labels[i] <= 2 * 104
