40 Tips for getting PHP code to fly (improve PHP efficiency) 1. If a method can be static, then declare that he is static, the speed can be increased by 1/4;2.echo is more efficient than print, because Echo has no return value, and print returns an integer type;3. Set the maximum number of cycles before the loop, not in the loop;4. Destroy the variable to release the memory, especially the large array;5. Avoid using magic methods like __get, __set,

set framework? The Java Collection Framework provides common algorithm implementations, such as sorting and searching. The collections class contains these method implementations. Most algorithms manipulate the list, but some of them are available for all types of collections. Some algorithms have sort, search, mixed, and maximum minimum values.39. What is an O in uppercase? Give me a few examples? The uppercase O describes the performance of an algorithm in terms of a series of elements in the

Python Advanced (40)-Data visualization using Matplotlib for drawing preface?? Matplotlib is an open source project based on the Python language, designed to provide Python with a data-drawing package. I'll cover the core objects of the Matplotlib API in this article, and explain how to use these objects to implement the drawing. In fact, Matplotlib's object system is rigorous and interesting, which provides a great space for users to play. Once the u

used append () method is a synchronous method, we write code repeatedly append string, which means to be repeated locking-to-unlock, which is bad for performance, Because this means that the Java virtual machine on this thread is repeatedly switching between the kernel state and the user state, so the Java virtual opportunity will append the code of the method calls several times to do a lock coarsening operation, the operation of multiple append extended to the Append method, the tail, becomes

algorithms manipulate the list, but some of them are available for all types of collections. Some algorithms have sort, search, mixed, and maximum minimum values.39. What is an O in uppercase? Give me a few examples?The uppercase O describes the performance of an algorithm in terms of a series of elements in the data structure. The collection class is the actual data structure, and we typically use the uppercase O to select the collection implementation based on time, memory, and performance. F

for an array or list is O (n), because we need to iterate through all the elements to find the elements we need.40. What are the best practices related to the Java collection framework?(1) Select the correct collection type as needed. For example, if you specify a size, we will choose an array instead of a ArrayList. If we want to traverse a map in order of insertion, we need to use TreeMap. If we don't want to repeat, we should use set.(2) Some coll

uppercase O to select the collection implementation based on time, memory, and performance. For example, the Get (index i) of the example 1:arraylist is a constant time operation that does not depend on the number of elements in the list. So its performance is O (1). Example 2: The performance of a linear search for an array or list is O (n), because we need to iterate through all the elements to find the elements we need.40. What are the best practi

result is 1. We can find the first 1 subscript position (recorded as Nth bit) as the basis for dividing the array. The nth bit of each number in the first Subarray is 1, and the nth bit for each number of the second sub-array is 0. For a number that occurs two times, the positive points are in the same sub-array. The two numbers that appear only once are divided into different sub-arrays.Suppose the array is {2,4, 3,6, 3,2,5,5}, xor result is 2, binary is represented as 0010. The second-to-last

It can lead to new ambiguity and the need for virtual inheritance.2.virtual inheritance increases the cost of size, speed, initialization (and assignment) complexity, and so on. If virtual base class does not carry any data, it will be the most useful case.3. Multiple inheritance does have a legitimate purp

Error pages are often overlooked by many designers, as they are rarely seen, or at least as planned (if they are often seen to be big). But we all know that this is going to happen. Visitors may either enter the wrong URL or try to find something that doesn't exist on your site. 404 pages will generally receive several visits, but accessing an error page is not part of a pleasant user experience. That's why many designers are now spending some extra time and effort on creating creative 404 pages
