Solution: Triples with Bitwise AND Equal To Zero
Explore an optimized approach to count triplets in an integer array that satisfy the bitwise AND condition equaling zero. Understand how to precompute pairwise bitwise AND results and use a hash map to efficiently find valid triplets, improving from a cubic to a quadratic time complexity solution.

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
