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
