In order to repair the fence, the farmer John cut a very long plank into n blocks. The length of the plank to be cut is l1,l2,l3 ... LN, the length of the uncut front plank is exactly the sum of the length of the wood cut. Each time the board is cut, the cost is the length of the plank. What is the minimum cost of requesting a plank to be cut in accordance with the target requirements? For example, a 21-length plank is cut into lengths of 13 and 8, wi

has been tangled in fence and atomic manipulation.Remember: Atomic manipulation is when multiple thread is prepared to write to the same data, and the purpose of atomic manipulation is to ensure that the data is read, modified, and written by only one thread. These three steps are not affected by other thread.Fence is to ensure that the thread's modifications to the data are discovered by other thread, and that thread continues to move forward after d

FFT in the analysis of spectrum analysis, there will be the following four aspects of the error:(1) Spectral aliasing: The Nyquist theorem is well known, so almost everyone knows that in order to keep the spectrum from aliasing, the spectral sampling spectrum is theoretically greater than or equal to the maximum frequency of the signal. What is the relationship between that and the time domain?The inverse of the sampling period is the spectral resolution, and the inverse of the highest frequency

Typically used to control thread waits, it allows a thread to wait until the timing is over before it starts executing.constructor function:public Countdownlatch (int count)//count count例如：在主线程中启动10个子线程去数据库中获取分页数据，需要等到所有线程数据都返回之后统一做统计处理public class Countdownlatchdemo implements runnable{private static final Countdownlatch end = new Countdownlatch (10);@Overridepublic void Run () {SYSTEM.OUT.PRINTLN ("Thread

Problem descriptionThere is an onion on the m*m square, you need to fix some fences to surround them. A fence is a closed pattern that is built along the grid (that is, a circle). Each fence should be disjoint, non-overlapping, and not included with each other. If you fix a maximum of K fences, what is the minimum length of all fences? Input formatThe first row of three integers n,m,k.The next n rows of two

Fence Cyclicbarrier are similar to latching countdownlatch, which can be said to be counted, to block a group of threads from knowing that an event occurred. The difference is that latching is used to wait for events, while fences are used to wait for other threads.In one of the previous implementations of countdownlatch--latching, it was mentioned in Countdownlatch that there is a counter in which a thread completes a task and calls the countdown met

The content of a well-known data structure class. It is used to process the encoding. To be accurate, it can be decompressed. It is a lossless compression. It is used to make statistics on the given characters, then, a ing table of different lengths is constructed based on statistics, and the original content is restored Based on the ing table. This question is a fixed length is worth the fence L, now want n boards to maintain this

Fences are similar to latching, but they are different. 1. The latch is used to wait for the event, and the fence is used to wait for the other threads. What do you mean? The event that the lock is used to wait is the countdown event, which is only possible if the thread that was waiting before execution of the countdown event is likely to continue; And the fence has no similar Countdown event control thre
