2611\. Mice and Cheese

Medium

There are two mice and `n` different types of cheese, each type of cheese should be eaten by exactly one mouse.

A point of the cheese with index `i` (**0-indexed**) is:

*   `reward1[i]` if the first mouse eats it.
*   `reward2[i]` if the second mouse eats it.

You are given a positive integer array `reward1`, a positive integer array `reward2`, and a non-negative integer `k`.

Return _**the maximum** points the mice can achieve if the first mouse eats exactly_ `k` _types of cheese._

**Example 1:**

**Input:** reward1 = [1,1,3,4], reward2 = [4,4,1,1], k = 2

**Output:** 15

**Explanation:** In this example, the first mouse eats the 2nd (0-indexed) and the 3rd types of cheese, and the second mouse eats the 0th and the 1st types of cheese. The total points are 4 + 4 + 3 + 4 = 15. It can be proven that 15 is the maximum total points that the mice can achieve.

**Example 2:**

**Input:** reward1 = [1,1], reward2 = [1,1], k = 2

**Output:** 2

**Explanation:** In this example, the first mouse eats the 0th (0-indexed) and 1st types of cheese, and the second mouse does not eat any cheese. The total points are 1 + 1 = 2. It can be proven that 2 is the maximum total points that the mice can achieve.

**Constraints:**

*   1 <= n == reward1.length == reward2.length <= 105
*   `1 <= reward1[i], reward2[i] <= 1000`
*   `0 <= k <= n`
