1005 - Maximize Sum Of Array After K Negations\.
Easy
Given an integer array `nums` and an integer `k`, modify the array in the following way:
* choose an index `i` and replace `nums[i]` with `-nums[i]`.
You should apply this process exactly `k` times. You may choose the same index `i` multiple times.
Return _the largest possible sum of the array after modifying it in this way_.
**Example 1:**
**Input:** nums = [4,2,3], k = 1
**Output:** 5
**Explanation:** Choose index 1 and nums becomes [4,-2,3].
**Example 2:**
**Input:** nums = [3,-1,0,2], k = 3
**Output:** 6
**Explanation:** Choose indices (1, 2, 2) and nums becomes [3,1,0,2].
**Example 3:**
**Input:** nums = [2,-3,-1,5,-4], k = 2
**Output:** 13
**Explanation:** Choose indices (1, 4) and nums becomes [2,3,-1,5,4].
**Constraints:**
* 1 <= nums.length <= 104
* `-100 <= nums[i] <= 100`
* 1 <= k <= 104
