2561\. Rearranging Fruits

Hard

You have two fruit baskets containing `n` fruits each. You are given two **0-indexed** integer arrays `basket1` and `basket2` representing the cost of fruit in each basket. You want to make both baskets **equal**. To do so, you can use the following operation as many times as you want:

*   Chose two indices `i` and `j`, and swap the ith fruit of `basket1` with the jth fruit of `basket2`.
*   The cost of the swap is `min(basket1[i],basket2[j])`.

Two baskets are considered equal if sorting them according to the fruit cost makes them exactly the same baskets.

Return _the minimum cost to make both the baskets equal or_ `-1` _if impossible._

**Example 1:**

**Input:** basket1 = [4,2,2,2], basket2 = [1,4,1,2]

**Output:** 1

**Explanation:** Swap index 1 of basket1 with index 0 of basket2, which has cost 1. Now basket1 = [4,1,2,2] and basket2 = [2,4,1,2]. Rearranging both the arrays makes them equal.

**Example 2:**

**Input:** basket1 = [2,3,4,1], basket2 = [3,2,5,1]

**Output:** -1

**Explanation:** It can be shown that it is impossible to make both the baskets equal.

**Constraints:**

*   `basket1.length == bakste2.length`
*   1 <= basket1.length <= 105
*   1 <= basket1[i],basket2[i] <= 109
