/*
Q. Given an array of integers, find all unique triplets (a, b, c) in the array such that their sum equals zero (a + b + c = 0).

Examples:
- Given an array: [1, 2, 0] returns: []
- Given an array: [-1, 0, 1, 0, 1] returns: [[-1, 0, 1]]
- Given an array: [-5, -1, 0, 1, 4, -1] returns: [[-5,1,4], [-1,0,1]]
