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...
Is there any way to do this using STL (as i want to be efficient my code needs to sort anout 1000 entries) for eg. let my vector be (1.0,4.1,3.1,2.3) then i want the output vector to be ( 1,4,3,2) // indices of original vector in sorted order ...
Call it like STL as well Note merge_sort_s,merge_sort_buffer_s,tim_sort_sis the safe copy version if you overload operator=and do something different Performance Run the codesorttest.cpp, it will output the result Build withg++ -std=c++03 -O3 sorttest.cppon Centos 7 x64, gcc version...

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...
