iterator Generally speaking, the process of extracting data from an object in turn is called traversal, and this means is called iteration (repeatedly execute a certain code block, and take the result of each iteration as the initial value of the next iteration). Iteratable object: refers to the object that can be used for... in... Loop, such ...

1. Process control theory Process control (also known as control process) means program When running, individual instructions (or statements subroutine )Run or evaluation The order of. That is, the execution process of the control program. The execution process is divided into: sequential structure (all the codes we wrote before are sequential ...

AQS implementation principle of concurrent programming series1. What is AQS?AQS (AbstractQueuedSynchronizer), an abstract queue synchronizer, is the basis of many Lock locks and synchronization components in juc, such as CountDownLatch, ReentrantLock, ReentrantReadWriteLock, Semaphore, etc. it provides interfaces or specific implementations for ...

Special note: This is really not the title party. I have written code for 20 + years. I really think go fuzzing is the most awesome code self-test method I have ever seen. When I used the AC automata algorithm to improve the keyword filtering efficiency (by ~ 50%) and the processing mechanism of mapreduce for panic, I found the edge bug throu ...

preface For example, I have implemented the requirements on NGUI, but now NGUI has not been used for many years. Now the requirements need to continue to be implemented on the UGUI version. I feel that they can be implemented quickly with components such as grid and ContentSizeFitter. After tossing for an hour, it has taken shape. I'll share i ...

Ordinary segment treeProblem introductionGiven that a sequence has n (n < = 100000) elements, there are the following two basic operationsQuery: find the sum of all elements in a given interval [l..r]Modify: modify the value of an element.Task: output the value of each query.Task quantity m (m < = 100000), only the above two operations.Na ...

1, Foreword This article will explore TimelineView in detail, starting with the most common usage. However, I think the greatest potential lies in the combination of TimelineView and the existing animation we already know. With a little creativity, this combination will let us finally make the animation of "key frame class". 2, Co ...
