vector元素排序并获取排序下标 //vector排序vector<int> v1,v2,res;v1.push_back(5);v1.push_back(2);v1.push_back(9);v2=v1;sort(v1.begin(),v1.end(),greater<int>()); //降序排列vector<int>::iterator iter;for (int i=0;i<v1.size();i++){ iter = find(v2.begin(), v2.end(), v1[i]); res.push_back(iter - v2.begin()); }
v1为排序好的值，res为排序完的下标
