常见的进程调度算法 1.先来先服务（FCFSFirstCome,FirstServed）。这是一种最简单得调度算法。顾名思义先到达的进程会先得到CPU的控制权。它的实现非常简单，但缺点也很明显。如果一个进程执行时间较长，后续的所有进程都得等待，这样就容易造成饥饿现象和较长的平均等待时间。2.短作业优先（SJF，ShortestJobFirst）...
短作业优先(SJF, Shortest Job First):优先调度预计运行时间最短的进程。这种方式可以减少等待时间,但是难以预知进程的实际运行时间,并且可能导致长作业饥饿。 最短剩余时间优先(SRTF, Shortest Remaining Time First):是SJF的一种抢占式变体,如果新到的进程需要的时间比当前运行的进程的剩余时间少,调度器将抢占当前进程。

The word binary means two. Thus it's evident that the algorithm must have some sort of connection with 2. Binary search is one of the most popular algorithms which searches a key from a sorted range in logarithmic time complexity. First, we need a sorted range for the binary search to ...
2-37(b), spend most of their time waiting for I/O. The former are called compute-bound; the latter are called I/O-bound. When to Schedule A nonpreemptive scheduling algorithm picks a process to run and then just lets it run until it blocks (either on I/O ...
Reversing three times is simplest but moves every element exactly twice, takes O(N) time and O(1) space It is possible to circle shift an array moving each element exactly once also in O(N) time and O(1) space (https://stackoverflow.com/questions/876293/fastest-algorithm-for-circle-...
When I was preparing for the C_TM_95 Exam, I couldn’t find any right material to pass it at my first attempt. But ExamBoosts helped me timely, I'm very happy. Kay 26 days ago I'm happy to tell you that I have passed C_TM_95 exam today, there are 5 new questions in real...

As seen in class, having a container that permits random access allows for the application of the efficient std::sort algorithm. The latter however depends on the availability of STL random-access iterators into the elements of the container. An implementation of ...
