Sorting and Two Pointers Approach

  1. Sort the array nums in ascending order.
  2. Initialize an empty set distinctAverages to store the distinct averages.
  3. Set two pointers, left at the start of the array and right at the end of the array.
  4. While left is less than right: a. Calculate the average of nums[left] and nums[right]. b. Add the calculated average to the set distinctAverages. c. Increment left and decrement right.
  5. Return the size of the set distinctAverages, which represents the number of distinct averages calculated.
