Solution: Triples with Bitwise AND Equal To Zero
Explore how to efficiently count triplets in an integer array where the bitwise AND of the three elements is zero. Learn to use hashing to precompute pairwise AND results and then check these with individual elements, reducing computational complexity from brute force to a manageable O(n²) approach.

Statement
You’re given an array of integers called nums. Your task is to count how many triplets of indexes (i, j, k) satisfy the condition nums[i] & nums[j] & nums[k] == 0, where & is the bitwise AND operator and ijk
