Solution: Triples with Bitwise AND Equal To Zero
Understand how to solve the problem of counting triplets where the bitwise AND of three numbers equals zero. Learn to implement a two-phase solution using a hash map to precompute pairwise AND frequencies, then combine results to find valid triplets efficiently. Explore the algorithm's time and space complexity to optimize your code.

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
