Mean of Array After Removing Some Elements
In this lab, you will implement a function to calculate the mean of the remaining integers of an array after removing the smallest 5% and the largest 5% of the elements. Your solution should correctly handle arrays of varying sizes and values, as long as they follow the constraints provided.
The function must return the mean, and answers within a 10-5 range of the actual answer will be accepted. Keep in mind that you should use ESM import/export everywhere.
To better understand the problem, take a look at the following examples:
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
Make sure your function follows these constraints:
20 <= arr.length <= 1000arr.lengthis a multiple of20.0 <= arr[i] <= 105
