There are n
workers. You are given two integer arrays quality
and wage
where quality[i]
is the quality of the ith
worker and wage[i]
is the minimum wage expectation for the ith
worker.
We want to hire exactly k
workers to form a paid group. To hire a group of k
workers, we must pay them according to the following rules:
Given the integer k
, return the least amount of money needed to form a paid group satisfying the above conditions. Answers within 10-5
of the actual answer will be accepted.
\n
Example 1:
\n\n\nInput: quality = [10,20,5], wage = [70,50,30], k = 2\nOutput: 105.00000\nExplanation: We pay 70 to 0th worker and 35 to 2nd worker.\n\n\n
Example 2:
\n\n\nInput: quality = [3,1,10,10,1], wage = [4,8,2,2,7], k = 3\nOutput: 30.66667\nExplanation: We pay 4 to 0th worker, 13.33333 to 2nd and 3rd workers separately.\n\n\n
\n
Constraints:
\n\nn == quality.length == wage.length
1 <= k <= n <= 104
1 <= quality[i], wage[i] <= 104
有 n
名工人。 给定两个数组 quality
和 wage
,其中,quality[i]
表示第 i
名工人的工作质量,其最低期望工资为 wage[i]
。
现在我们想雇佣 k
名工人组成一个工资组。在雇佣 一组 k
名工人时,我们必须按照下述规则向他们支付工资:
给定整数 k
,返回 组成满足上述条件的付费群体所需的最小金额 。在实际答案的 10-5
以内的答案将被接受。。

示例 1:
\n\n\n输入: quality = [10,20,5], wage = [70,50,30], k = 2\n输出: 105.00000\n解释: 我们向 0 号工人支付 70,向 2 号工人支付 35。\n\n
示例 2:
\n\n\n输入: quality = [3,1,10,10,1], wage = [4,8,2,2,7], k = 3\n输出: 30.66667\n解释: 我们向 0 号工人支付 4,向 2 号和 3 号分别支付 13.33333。\n\n
\n\n
提示:
\n\nn == quality.length == wage.length
1 <= k <= n <= 104
1 <= quality[i], wage[i] <= 104
