end does not move. but Deuqe, after all, cannot be directly a stack, and it does not directly meet your requirements , because you cannot prevent others from moving your things on the other end of the way. You need to wrap it up and make some restrictions so that it can only be inserted and deleted at one end. That means you have to provide a "socket", the "socket" on the deque, the other end in your program, you can use the stack structure. And the stack is the "socket" that connects the Deque

# function: # 1. Prevent others from adding new attributes to existing instances;# 2. Optimize memory and execution speed; # The essence of optimization: No longer use dictionaries to store instance data, but more compact array structure; # Especially if you need to create a large number of objects; # attached: When inheriting a base class containing the __slot__ attribute, subclasses also define __slot__ to store their own properties . # Otherwise, the

data is retained only for one copy. 25, enhanced for loop foreach is a syntactic sugar, the collection class wants to use must implement the Iterable interface, because he is the bottom of the iterable iterator traversal. The array does not implement an iterator interface, and the underlying loop iterates through the data reference implementation. That is, the enhanced for loop is implemented by invoking the underlying. 26, Hashtable and HashMap difference, Hashtable is the old API left, all hi

supports the removal of elements through the iterator remove, Set.remove, RemoveAll, Retainall, and clear operations and removes the corresponding mappings from the map. It does not support add and addall operations. (3) set Returns a collection view of all mappings contained in a map clock. This collection is supported by the map, which is reflected in the collection and vice versa. When an iterator is traversing a collection, if the map is modified (except for the entry of the iterator itsel

operation of data changes So JAVA5 provides read-write lock which supports multithreading read operation, multithreading, mutual exclusion, and multithreading writing and writing mutually exclusive. Read operation is not mutually exclusive this helps improve performance, this is not before JAVA5two.

re-solve a few classic Huawei C language Face Test 1 , find the wrong void Test1 () { char string[10] char* str1= "0123456789"; strcpy (string, str1); here the string array is out of bounds because the string length is 10 and there is a Terminator '/0 '. So there are a total of 11 characters in length. The string array has a size of 10, and here it crosses. PS: When using the strcpy function, be sure to be aware that the previous destination array

iOS face Test 12-runloop is what. Runloop is literally the meaning of running loops, which is not bad, it is indeed a concept of the loop, or exactly the loop in the thread. Some programs are a circle, this circle is essentially the so-called runloop, is a cycle, but this cycle to add a lot of features. First of all, the beginning of the loop body needs to detect whether there is a need to deal with the event, if there is to deal with, if not then go

load Java extension libraries. The implementation of the Java virtual machine provides an extension library directory. The class loader finds and loads Java classes in this directory.3. Systems Class Loader (System class loader): It loads Java classes based on the Java application's Classpath (CLASSPATH). In general, Java-applied classes are loaded by it. It can be obtained by Classloader.getsystemclassloader ().4. User-defined ClassLoader, implemented by inheriting the Java.lang.ClassLoader cl
