Solution: Triples with Bitwise AND Equal To Zero
Explore how to efficiently count triplets of integers where the bitwise AND equals zero by precomputing pairwise AND results and using a hash map. Understand the step-by-step approach to reduce complexity from O(n³) to O(n²) while handling constraints up to 2¹⁰, and learn how to implement this in Go.

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
