() 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

In the compilation of games, there are inevitably a lot of application data structures. Some simple games are only composed of several data structures. Therefore, data structures play an important role in game programming.This art

the x in parentheses to a floating-point type;Complex (x) converts the x in parentheses into a complex number;For example:---------------Convert 666 of string types to integer----------------------->>>Print(Type (int ("666")))class 'int'>---------------Convert 666 of string types to floating-point--------------------->>>Print(Type (float ("666")))class 'float'>>>>Print(Float ("666"))666.0--------------Convert 666 of string types to plural------------------------>>>Print(Complex ("666"))(666+0J)

Concepts: Arrays and generalized tables can be thought of as extensions of linear tables in the following meanings, and the data elements in the table are themselves a data structure. Generalized tables can also be regarded as the generalization of linear tables. (1) The elements of a generalized table can be child tables, and the elements of a child table can also contain child tables. (2) The list can be

the space as a linked table node .The following from Baidu intercepted a picture, you can clearly understand the structure of the reaction below. For example, I have a bunch of data {1,12,26,337,353 ...}, and my hashing algorithm is H (key) =key MoD 16, the hash value of the first Data 1 f (1) = 1, inserted after the 1 node, the second data 12 hash value f (12)

is true. is called a short-circuit operation because if the value of the expression on the left side of is false, the expression on the right will be shorted out directly and will not be evaluated.Most of the time we may need to use instead of , for example, to verify that the user's name is not NULL and is not an empty string when validating the login, it should be written as username! = null !username.equals (""), The order of the two cannot be exchanged,You cannot use the operator, becaus

again, this time based on the 10-bit value (IBID.), the allocation result (logical imagination) as shown:After the assignment ends. Next, the data in all buckets (the same principle as above) is then re-collected serially, resulting in the following data series:14 22 28 39 43 55 65 73 81 93Hill sortAn array of n=10 49, 38, 65, 97, 26, 13, 27, 49, 55, 4 for exampleFirst time gap = 10/2 = 549 38 65 97 26 13

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

can quickly find its associated multicast group database entries U32 queries_sent;//the number of times a query package has been sent }; Where the port list is used to add all the corresponding bridges to the addr of the multicast group Next points to the next multicast port, and the next multicast group address is addr, only the port value is different. Where mglist is used to add the multicast port to the Mglist linked list of port, through the mglist linked list of the bridge port, can find

, 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. 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. If you initialize to a very large array size, it will be wasted memory space, if it is small, the number of subsequent

StackStack, which is called a stack, is a container that can be stored in data elements, access elements, delete elements, and it is characterized only by allowing the addition of data (English: Push) and output data (English: Pop) to one end of the container (called the stack Top indicator, English: top). Without a location concept, it is guaranteed that any ele

){ if(Array[j] key) {Array[i+ +] = Array[j];//A[i] = a[j]; i + = 1; Break; }; } for(; i ){ if(Array[i] >key) {Array[j--] =Array[i]; Break; }}} Array[i]=key; Sort (0, i); Sort (i+ 1, numsize); }} sort (0, Array.Length); returnArray;}There is also an easy-to-understand approach:Set two empty arrays left and right, traverse the entire array, and push in to leave if it encounters less critical

List is an interface, ArrayList and LinkedList are two implementation classes, they implement the same way, in fact LinkedList is the real chain list (if not clear what is linked list, need to understand the knowledge of related data structure, this is not one or two words can be said clearly), And ArrayList is implemented by an array, which is not a real linked list, it sets an initial capacity of an array at initialization time, and when there is no
