You could use STL nth_element instead: #include <algorithm> // Assuming you keep the elements in a vector v of size len std::nth_element( v.begin(), v.begin()+len/2, v.end() ); median = v[len/2]; //... or, if the elements are in a simple array v[len], then std::n...

排序是编程中很常用的操作。当要排序的数据量很大,无法一次装入内存时,就要使用外部排序。 外部排序通常的做法是先把数据分成多个可以一次装入内存的小段,对这些段分别使用内部排序,将排好序的段依次写入磁盘,再进行多路归并。 多路归并通常用败者树来加速,但既然stl里有现成的priority_queue,我们可以偷个懒,不去重复...
http://www.cplusplus.com/reference/stl/map/ : Internally, the elements in the map are sorted from lower to higher key value following a specific strict weak ordering criterion set on construction. You can copy all the contents of the map into a sequence of pair<double,double> and sort ...
