C ++ design mode: adapter mode (3) 4. Adapter mode Summary In Object Adapter mode, the adapter and the adapter are associated; in class adapter mode, the adapter and the adapter are inherited. Both the Object Adapter and the class adapter convert

C ++ implements heap sorting Heap sorting is a sort method that has the advantages of Merge Sorting and insert sorting. Its time complexity is O (nlgn), and it is also an in-situ Sorting Algorithm: at any time, only constant elements in the array
