For each element nums[i], we calculate two indices: leftIdx using a lowerBound function to find the first index where elements are not less than lower - nums[i]. rightIdx using an upperBound function to find the first index where elements exceed upper - nums[i]. The difference between these indices, adjusted by i, gives the count of valid pairs (i, j) for the current i. Summing up these counts across all i provides the total number of fair pairs within the specified range. This approach leverages binary search for efficient pair counting, achieving a time complexity of O(nlogn).
