Example:
Input: arr = [1, 5, 7, 1, 5], K = 6
Pairs: (1,5) at indices (0,1) and (0,3), but unique values?
Here values (1,5) is one pair. So answer = 1. TCS Coding Questions 2021 – Full Practice Paper

Approach (Logic): Manage four boundaries: top, bottom, left, right. Loop while top <= bottom and left <= right. Solve the following coding problems
