Given an array S of n integers, find three integers in S such that the sum is closest to a given number, target. Return the sum of the three integers. You may assume that each input would have exactly one solution.
    For example, given array S = {...

                                题目大意:先给定n个数字,现在要求算出这n个数字的两两之和保存到sum数组,然后在给定m个数,要求找到和每一个数最接近的sum[i];
挨个计算每个属于其他数之间的sum,然后排序;
查找时有两种方法:二分查找&&双向查找;当然二分查找的效率比后者高了很多,但是都能AC。
提供一条新思路,并不一定非要用二分。
双向查找:
