Given an array S of n integers,
are there elements a, b, c in S such that a + b + c = 0?
Note:
Elements in a triplet (a,b,c)
must be in non-descending order. (ie, a ≤ b ≤ c)
The solution set must not contain duplicate triplets.
For example,
given array S = {-1 0 1 2 -1 -4},
A solution set is:
(-1, 0, 1)
(-1, -1, 2)
