extends Object

1248 - Count Number of Nice Subarrays\. Medium Given an array of integers `nums` and an integer `k`. A continuous subarray is called **nice** if there are `k` odd numbers on it. Return _the number of **nice** sub-arrays_. **Example 1:** **Input:** nums = [1,1,2,1,1], k = 3 **Output:** 2 **Explanation:** The only sub-arrays with 3 odd numbers are [1,1,2,1] and [1,2,1,1]. **Example 2:** **Input:** nums = [2,4,6], k = 1 **Output:** 0 **Explanation:** There is no odd numbers in the array. **Example 3:** **Input:** nums = [2,2,2,1,2,2,1,2,2,2], k = 2 **Output:** 16 **Constraints:** * `1 <= nums.length <= 50000` * `1 <= nums[i] <= 10^5` * `1 <= k <= nums.length`
