() 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

The stack only allows access to the last inserted data item.
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

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

An ordered array can be found by a particular algorithm faster than without an array, and we'll talk about sorting algorithms later on.③, delete slowly, according to the value of the element is deleted, we need to find the location of the element, and then the value behind the element to move the whole forward one position.

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

Then we put one of the 1 in the position of the second position of the 1 b[1], while c[1]-1, because we have already lined up a 1.Next, I=1,a[1]=2,c[2] is less than or equal to 2 of the number of occurrences, c[2]=4, then to rank it in fourth place, that is b[3] position, while c

It also takes a lot more time.④, arrays once created, the size is fixed, you cannot dynamically expand the number of elements of the array.

the process data in the lookup table is a change, there is a delete or insert operationBinary sort tree: The structure of a tree is usually not generated at once, but in the process of finding it, inserting it when there is no keyword equal to the given node in the tree. 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
