1619 - Mean of Array After Removing Some Elements\. Easy Given an integer array `arr`, return _the mean of the remaining integers after removing the smallest `5%` and the largest `5%` of the elements._ Answers within 10-5 of the **actual answer** will be considered accepted. **Example 1:** **Input:** arr = [1,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,3] **Output:** 2.00000 **Explanation:** After erasing the minimum and the maximum values of this array, all elements are equal to 2, so the mean is 2. **Example 2:** **Input:** arr = [6,2,7,5,1,2,0,3,10,2,5,0,5,5,0,8,7,6,8,0] **Output:** 4.00000 **Example 3:** **Input:** arr = [6,0,7,0,7,5,7,8,3,4,0,7,8,1,6,8,1,1,2,4,8,1,9,5,4,3,8,5,10,8,6,6,1,0,6,10,8,2,3,4] **Output:** 4.77778 **Constraints:** * `20 <= arr.length <= 1000` * `arr.length` **is a multiple** of `20`. * 0 <= arr[i] <= 105
