Solution: Triples with Bitwise AND Equal To Zero
Explore how to efficiently solve the problem of counting triplets in an array where their bitwise AND is zero. Understand a two-phase approach using a hash map for precomputed pairwise AND frequencies, enabling a reduction from cubic to quadratic time complexity in JavaScript.

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
