Solution: Triples with Bitwise AND Equal To Zero

Explore how to count the number of triplets in an array whose bitwise AND equals zero. Learn to use hashing for pairwise bitwise results and optimize the algorithm from cubic to quadratic time. Understand the implementation details and analyze time and space complexity while applying bitwise manipulation in Go.

We'll cover the following...

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 0≤0 \leq i,, j,, k ...
