思路简单：
（1） 三重 for ，符合a+b+c=0的 a,b,c保存在tuple里
（2）tuple保存在set 中，一可去重，二可保持字典序
（3）简单代价就是复杂度很高，O(n^3*logn)
typedef tuple triplet;
triplet sort3(int a,int b,int c){
if(ac){
swap(b,c);...

title:
A Pythagorean triplet is a set of three natural numbers, a
b
c, for which,
a2 + b2 =
c2
For example, 32 + 42 = 9 + 16 = 25 = 52.
There exists exactly one Pythagorean triplet for wh...

【题目】
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...
