vector不帶排序功能,標準容器只有l(wèi)ist有自己的sort()所用的std::sort()在<algorithm>中,一般接受兩個參數(shù):開頭的迭代器i1和末尾的i2,并對[i1,i2)區(qū)間元素排序另外還有接受三個參數(shù)的sort(),第三個參數(shù)是一個...
我利用了algorithm里的random_shuffle函數(shù),這個函數(shù)是隨機排序的。我的思路是用另一個vector取出不要固定的元素做隨機排序,然后把固定元素還原得到重排后的vector:include<iostream>include<algorithm>include<vector>usi...

structnode{intnum;structnode*next;};//函數(shù)聲明structnode*creat();voidprint();main(){structnode*head;head=NULL;//②建一個空表head=creat(head);/*創(chuàng)建單鏈表*/print(head);/*打...
vector<int>a;//定義一個容器while(cin>>x&&x!='e'){a.push_back(x);//變量x在容器a尾部入棧}sort(a.begin(),a.end());//排序for(inti=0;i<a.size();i++)//輸出(a.size():讀取容器a...
for(vector<int>::size_typeiy=0;iy<ivec.size()-ix;++iy)中,ivec.size()-ix還要再-1;另外說句題外話,swap函數(shù)可以聲明成inline,不然函數(shù)重復(fù)調(diào)用開銷挺大的

Collections.sort(List,Compare),如果泛型是JDK提供的如基本類型或者String則不需要COmpareTo接口,如果自定義的需要實現(xiàn)CompareTo接口
你好,可以利用map實現(xiàn)。以下是代碼,請參考://copyright@quark//date:2010-10-19include<vector>include<iostream>includeinclude<algorithm>usingnamespacestd;voidpaixu(vector<int>&ivec,intto...
