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 of20
.0 <= arr[i] <= 105
