This is the 33rd Video of our Playlist "BInary Search : Popular Interview Problems" by codestorywithMIK

In this video we will try to solve a medium Array Binary Search Problem : Count the Number of Fair Pairs | Detailed Explanation | Leetcode 2563 | codestorywithMIK

I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Summary :
The approach involves sorting the nums array first to make pair searching easier. 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).
