//vector的排序
vector<int>v;
sort(v.begin(),v.end());升序
sort(v.rbegin(),v,rend());降序
//sort of vector<pair<int,int> >v;
v.push_back({1,5});
v.push_back({2,3});
v.push_back({1,2});
sort(v.begin(), v.end());//输出{1，2}，{1，5}，{2，3}
//sort of vecto<tuple<int,int,int> > v;
v.push_back({2,1,4});
v.push_back({1,5,3});
v.push_back({2,1,3});
sort(v.begin(), v.end());
//有is~
vector<pair<int,int> >v;很常用
还有一种写法
1 void cmp(pair<int,int> a,pair<int,int> b) 2 { 3 if(a.first==b.first)return a.second<s.b.second; 4 5 return a.first<b.first; 6 } 7 8 9 10 pair<int,int> a,pair<int,int> b; 11 12 sort(a,b,cmp);
//string bool comp(string a, string b) { if (a.size() != b.size()) return a.size() < b.size(); return a < b; } string s="monkey"; sort(s.begin(),s.end());//output:ekmnoy
