分享unique_copy不是拷贝不重复的元素吗
#include<iostream>
#include<list>
#include<string>
#include<algorithm>
using namespace std;
int main()
{
list<string> a = { "abc","kjdfs","abc","kdf","kjdfs" };
list<string> b;
unique_copy(a.begin(), a.end(), back_inserter(b));
for (auto k : b)
cout << k << ends;
system("pause");
return 0;
}
为什么全拷贝进去了

删除的是连续的相同元素，你的两个"abc"并不连续

http://en.cppreference.com/w/cpp/algorithm/unique_copy
Copies the elements from the range [first, last), to another range beginning at d_first in such a way that there are no consecutive equal elements. Only the first element of each group of equal elements is copied.

类属性算法unique的作用是从输入序列中“删除”所有相邻的重复元素。
