3194 - Minimum Average of Smallest and Largest Elements.

Easy

You have an array of floating point numbers averages which is initially empty. You are given an array nums of n integers where n is even.

You repeat the following procedure n / 2 times:

  • Remove the smallest element, minElement, and the largest element maxElement, from nums.
  • Add (minElement + maxElement) / 2 to averages.

Return the minimum element in averages.

Example 1:

Input: nums = [7,8,3,4,15,13,4,1]

Output: 5.5

Explanation:

Stepnumsaverages
0[7,8,3,4,15,13,4,1][]
1[7,8,3,4,13,4][8]
2[7,8,4,4][8, 8]
3[7,4][8, 8, 6]
4[][8, 8, 6, 5.5]

The smallest element of averages, 5.5, is returned.

Example 2:

Input: nums = [1,9,8,3,10,5]

Output: 5.5

Explanation:

Stepnumsaverages
0[1,9,8,3,10,5][]
1[9,8,3,5][5.5]
2[8,5][5.5, 6]
3[][5.5, 6, 6.5]

Example 3:

Input: nums = [1,2,3,7,8,9]

Output: 5.0

Explanation:

Stepnumsaverages
0[1,2,3,7,8,9][]
1[2,3,7,8][5]
2[3,7][5, 5]
3[][5, 5, 5]
