Solution: Triples with Bitwise AND Equal To Zero

Understand how to efficiently count triplets in an array where the bitwise AND of three elements results in zero. Explore a two-phase approach using precomputed pairwise bitwise AND results and frequency mapping. Learn to optimize from a brute-force cubic solution to a more efficient quadratic time algorithm in Python.

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 00 \leq i,, j,, k ...
