Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0.
Notice that the solution set must not contain duplicate triplets.
Example 1:
Input: nums = [-1,0,1,2,-1,-4] Output: [[-1,-1,2],[-1,0,1]]
Example 2:
Input: nums = [] Output: []
Example 3:
Input: nums = [0] Output: []
Constraints:
0 <= nums.length <= 3000-105 <= nums[i] <= 105
