list是一种线性复杂度的容器,很快

#include <bits/stdc++.h> using namespace std; void print(list<int> & l)
{
list<int>::iterator it;
for(it = l.begin() ; it != l.end() ; it++)
{
cout << *it << " ";
}
cout << endl;
} int main()
{
list <int> l1;
list <int> l2; rep(i,,)
{
l1.push_back(i);
} print(l1); rep(i,,)
{
l2.push_back(i);
} print(l2); list<int>::iterator it; it = l2.begin()++; l2.splice(l2.begin(),l1);//将l1中元素开始合并到l2上,起始点为l2.begin(),最后再删除掉l1 print(l2); it = l2.begin(); l1.splice(l1.begin(),l2, it); //将l2上it位置处的元素归并到l1上并从l2中删掉 print(l1); l2.sort(); print(l2); l2.unique(); //去重 print(l2); rep(i,,)
{
l1.push_back(i);
} print(l1); l2.merge(l1); //两个链表进行排序才能使用这个,归并以后的结果也是排序的结果 print(l1);
print(l2);
return ;
}

其他常用的函数:

push_back();
push_front();
erase();
pop_front();
pop_back();
remove();
clear();
