You are given an integer array nums.
An array is called parity alternating if for every index i where 0 <= i < n - 1, nums[i] and nums[i + 1] have different parity (one is even and the other is odd).
In one operation, you may choose any index i and either increase nums[i] by 1 or decrease nums[i] by 1.
Return an integer array answer of length 2 where:
answer[0] is the minimum number of operations required to make the array parity alternating.answer[1] is the minimum possible value of max(nums) - min(nums) taken over all arrays that are parity alternating and can be obtained by performing exactly answer[0] operations.An array of length 1 is considered parity alternating.
Example 1:
Input: nums = [-2,-3,1,4]
Output: [2,6]
Explanation:
Applying the following operations:
nums[2] by 1, resulting in nums = [-2, -3, 2, 4].nums[3] by 1, resulting in nums = [-2, -3, 2, 3].The resulting array is parity alternating, and the value of max(nums) - min(nums) = 3 - (-3) = 6 is the minimum possible among all parity alternating arrays obtainable using exactly 2 operations.
Example 2:
Input: nums = [0,2,-2]
Output: [1,3]
Explanation:
Applying the following operation:
nums[1] by 1, resulting in nums = [0, 1, -2].The resulting array is parity alternating, and the value of max(nums) - min(nums) = 1 - (-2) = 3 is the minimum possible among all parity alternating arrays obtainable using exactly 1 operation.
Example 3:
Input: nums = [7]
Output: [0,0]
Explanation:
No operations are required. The array is already parity alternating, and the value of max(nums) - min(nums) = 7 - 7 = 0, which is the minimum possible.
Constraints:
1 <= nums.length <= 105-109 <= nums[i] <= 109
