Solution: Triples with Bitwise AND Equal To Zero
Explore how to efficiently count triplets of integers in an array whose bitwise AND equals zero by precomputing pairwise AND results with a hash map. Understand the use of bitwise manipulation to reduce brute-force complexity from cubic to quadratic time, enabling faster problem-solving in coding interviews.

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
