() method in the Bubblesort.java program (listing 3.1) with the Oddevensort () method . Make sure it runs in a sort of different amount of data, and that you need to figure out the number of two scans. Parity Ordering is actually useful in multiprocessor environments where the processor can process each odd pair at the same time, and then handle even pairs at the same time. Because the odd pairs are independent of each other, each pair can be compar

, this time will not be faster than bubble sorting.Back to top 4, summaryThe above three kinds of sorting, bubbling, selecting, inserting with large O notation all require O (N2) time level. Bubbling sorting is not generally selected, although bubbling sort writing is the simplest, but the average performance is not to choose sort and insert sort well.Select sort to reduce the number of exchanges to the lowest, but the number of comparisons is quite large. Select sort can be applied when the amo

seen a lot about the drawbacks of arrays. If the insertion time in an unordered array is fast, but the lookup takes a slower time. It can be found quickly in an ordered array, but it takes a long time to insert. For both arrays, the delete operation time is also slow.If you have a data structure that takes any action, such as inserting, deleting, and looking up quickly (ideally an O (1) or O (Logn)), that's fine.Another problem with arrays is that wh

The queue only allows access to the first inserted data item.
A queue can be implemented as a circular queue, which is based on an array, and the array subscript wraps around the end of the array

Ordered array deletion (query + fill hole)

Why not use data to solve everythingAn unordered array is inserted (O (1) time), and the query spends (O (N) time). An ordered array query spends (O (logn) time), but inserts a missing cost (O (N) time). And the deletion takes (O (N) time). So a data structur

The characteristic is that the root node is larger than the left child, smaller than the right child. You can modify the pointer based on the node location when you delete the

has a specific value, and once found, you can display, delete, or otherwise manipulate the node.
The new node can be inserted in front of or behind a node of a particular value, first to traverse to find the node.
The double-ended list maintains a reference to the last node in the list, which is usually the same as the header, called Tailer.
Double-ended lists allow data items to be inserted at the end of a table.
