题目：给定一个数组，以及一个 target 值，target 表示目标和，要求在数组中找到两个数，xi，xj，使得 xi + xj = target。返回值是找到的两个数的下标索引，升序排序。假定至少存在一对解。
分析：对于要处理数组的问题，我们的理想状态都是给定的数组是有序的就好了，在有序后，我们就可以首位各放一个标记。类似于二分查找。

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 so...
