Given an array `nums` of integers, a move consists of choosing any element and decreasing it by 1.

An array `A` is a zigzag array if either:

- Every even-indexed element is greater than adjacent elements, ie. `A[0] > A[1] < A[2] > A[3] < A[4] > ...`
- OR, every odd-indexed element is greater than adjacent elements, ie. `A[0] < A[1] > A[2] < A[3] > A[4] < ...`

Return the minimum number of moves to transform the given array `nums` into a zigzag array.

Example 1:

    Input: nums = [1,2,3]
    Output: 2
    Explanation: We can decrease 2 to 0 or 3 to 1.

Example 2:

    Input: nums = [9,6,1,6,2]
    Output: 4

Constraints:

- `1 <= nums.length <= 1000`
- `1 <= nums[i] <= 1000`
