1343 - Number of Sub-arrays of Size K and Average Greater than or Equal to Threshold\. Medium Given an array of integers `arr` and two integers `k` and `threshold`, return _the number of sub-arrays of size_ `k` _and average greater than or equal to_ `threshold`. **Example 1:** **Input:** arr = [2,2,2,2,5,5,5,8], k = 3, threshold = 4 **Output:** 3 **Explanation:** Sub-arrays [2,5,5],[5,5,5] and [5,5,8] have averages 4, 5 and 6 respectively. All other sub-arrays of size 3 have averages less than 4 (the threshold). **Example 2:** **Input:** arr = [11,13,17,23,29,31,7,5,2,3], k = 3, threshold = 5 **Output:** 6 **Explanation:** The first 6 sub-arrays of size 3 have averages greater than 5. Note that averages are not integers. **Constraints:** *1 <= arr.length <= 105*1 <= arr[i] <= 104* `1 <= k <= arr.length` *0 <= threshold <= 104
