982 - Triples with Bitwise AND Equal To Zero\. Hard Given an integer array nums, return _the number of **AND triples**_. An **AND triple** is a triple of indices `(i, j, k)` such that: * `0 <= i < nums.length` * `0 <= j < nums.length` * `0 <= k < nums.length` * `nums[i] & nums[j] & nums[k] == 0`, where `&` represents the bitwise-AND operator. **Example 1:** **Input:** nums = [2,1,3] **Output:** 12 **Explanation:** We could choose the following i, j, k triples: (i=0, j=0, k=1) : 2 & 2 & 1 (i=0, j=1, k=0) : 2 & 1 & 2 (i=0, j=1, k=1) : 2 & 1 & 1 (i=0, j=1, k=2) : 2 & 1 & 3 (i=0, j=2, k=1) : 2 & 3 & 1 (i=1, j=0, k=0) : 1 & 2 & 2 (i=1, j=0, k=1) : 1 & 2 & 1 (i=1, j=0, k=2) : 1 & 2 & 3 (i=1, j=1, k=0) : 1 & 1 & 2 (i=1, j=2, k=0) : 1 & 3 & 2 (i=2, j=0, k=1) : 3 & 2 & 1 (i=2, j=1, k=0) : 3 & 1 & 2 **Example 2:** **Input:** nums = [0,0,0] **Output:** 27 **Constraints:** * `1 <= nums.length <= 1000` * 0 <= nums[i] < 216
