1619. Mean of Array After Removing Some Elements Easy

1/**
2 * [1619] Mean of Array After Removing Some Elements
3 *
4 * Given an integer array arr, return the mean of the remaining integers after removing the smallest 5% and the largest 5% of the elements.
5 * Answers within 10^-5 of the actual answer will be considered accepted.
6 *  
7 * Example 1:
8 * 
9 * Input: arr = [1,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,2,3]
10 * Output: 2.00000
11 * Explanation: After erasing the minimum and the maximum values of this array, all elements are equal to 2, so the mean is 2.
12 * 
13 * Example 2:
14 * 
15 * Input: arr = [6,2,7,5,1,2,0,3,10,2,5,0,5,5,0,8,7,6,8,0]
16 * Output: 4.00000
17 * 
18 * Example 3:
19 * 
20 * 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]
21 * Output: 4.77778
22 * 
23 *  
24 * Constraints:
25 * 
26 * 	20 <= arr.length <= 1000
27 * 	arr.length is a multiple of 20.
28 * 	<font face="monospace">0 <= arr[i] <= 10^5</font>
