# 3 Sum Zero - InterviewBit Solution

**Problem:** __3 Sum Zero__

### Problem Description:

Given an array S of n integers, are there elements a, b, c in S such that a + b + c = 0?

Find all unique triplets in the array which gives the sum of zero.

###### 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)
```
