2465. Number of Distinct Averages
You are given a 0-indexed integer array nums of even length.
As long as nums is not empty, you must repetitively:
- Find the minimum number in nums and remove it.
- Find the maximum number in nums and remove it.
- Calculate the average of the two removed numbers.
The average of two numbers a and b is (a + b) / 2.
- For example, the average of 2 and 3 is (2 + 3) / 2 = 2.5.
Return the number of distinct averages calculated using the above process.
Note that when there is a tie for a minimum or maximum number, any can be removed.
