2348 - Number of Zero-Filled Subarrays\. Medium Given an integer array `nums`, return _the number of **subarrays** filled with_ `0`. A **subarray** is a contiguous non-empty sequence of elements within an array. **Example 1:** **Input:** nums = [1,3,0,0,2,0,0,4] **Output:** 6 **Explanation:** There are 4 occurrences of [0] as a subarray. There are 2 occurrences of [0,0] as a subarray. There is no occurrence of a subarray with a size more than 2 filled with 0. Therefore, we return 6. **Example 2:** **Input:** nums = [0,0,0,2,0,0] **Output:** 9 **Explanation:** There are 5 occurrences of [0] as a subarray. There are 3 occurrences of [0,0] as a subarray. There is 1 occurrence of [0,0,0] as a subarray. There is no occurrence of a subarray with a size more than 3 filled with 0. Therefore, we return 9. **Example 3:** **Input:** nums = [2,10,2019] **Output:** 0 **Explanation:** There is no subarray filled with 0. Therefore, we return 0. **Constraints:** * 1 <= nums.length <= 105 * -109 <= nums[i] <= 109
