The array `nums` is called **alternating** if: `nums[i - 2] == nums[i]`, where `2 <= i <= n - 1`. `nums[i - 1] != nums[i]`, where `1 <= i <= n - 1`. In one **operation**, you can choose an index `i` and **change** `nums[i]` into **any** positive integer. Return _the **minimum number of operations** required to make the array alternating_. **Example 1:** ``` **Input:** nums = [3,1,3,2,4,3] **Output:** 3 **Explanation:** One way to make the array alternating is by converting it to [3,1,3,**1**,**3**,**1**]. The number of operations required in this case is 3. It can be proven that it is not possible to make the array alternating in less than 3 operations. ``` **Example 2:** ``` **Input:** nums = [1,2,2,2,2] **Output:** 2 **Explanation:** One way to make the array alternating is by converting it to [1,2,**1**,2,**1**]. The number of operations required in this case is 2. Note that the array cannot be converted to [**2**,2,2,2,2] because in this case nums[0] == nums[1] which violates the conditions of an alternating array. ``` **Constraints:** `1 <= nums.length <= 105` `1 <= nums[i] <= 105`",8 "test_case": [9 {10 "label": "Example 1",11 "input": "nums = [3,1,3,2,4,3]",12 "output": "3 "13 },14 {15 "label": "Example 2",16 "input": "nums = [1,2,2,2,2]",17 "output": "2 "18 }19 ],20 "constraints": [21 "nums[i - 2] == nums[i], where 2 <= i <= n - 1.",22 "nums[i - 1] != nums[i], where 1 <= i <= n - 1.",23 "1 <= nums.length <= 105",24 "1 <= nums[i] <= 105"25 ],26 "python_template": "class Solution(object):\n def minimumOperations(self, nums):\n \"\"\"\n :type nums: List[int]\n :rtype: int\n \"\"\"\n ",27 "java_template": "class Solution {\n public int minimumOperations(int[] nums) {\n \n }\n}",28 "metadata": {29 "func_name": "minimumOperations"30 }31}
