Description: 基本算法思想 OPT：该算法的基本思想是用二维数组page2[40][2] 的第一列存储装入内存的页面，而第二列用作标记位计数器。每当发生缺页时，就从内存中调出一页，首先将内存中的页面一一与要调入内存中的页面之后的页面比较，如果两个页面不相等，则内存中相应的页面的标记位计数器加一，直至到有相等的页面，则该页面的比较停止，再重复以上操作，直至内存中的页面全部比较完。然后找出内存中页面的标记位最大的页面，而该页就是要置换出来的页。 FIFO: 该算法的基本思想是用队列queue存储内存中的页面，队列的特点是先进先出，与该算法是一致的，所以每当发生缺页时，就从队头删除一页，即队头指针加一，而从队尾加入缺页，队尾指针加一。 LRU: 该算法的基本思想是用二维数组page2[40][2] 的第一列存储装入内存的页面，而第二列用作标记位计数器。每当使用页面时，该页面的标记位计数器加一。发生缺页时，就从内存中页面标记最小的一页，调出该页，并且该页后面的页面在数组中的位置前移，而缺页就放在数组后面。-basic algorithm thinking OPT : The basic idea of the algorithm is a two-dimensional array page2 [40] [2], the first storage pages loaded into memory, and the second for the markers out counter. Whenever there are missing pages, from memory a redeployment, the first memory pages on January 1 and transferred to the memory page after page, two pages, if not equal, then the corresponding memory pages marked increase a bit counter, until the equivalent of a page, the page more stop and then to repeat the operation, until the memory of all the pages compared End. Then find memory pages marking the largest-page, the page is to the replacement page. FIFO : The basic idea of the algorithm is used queue queue storage memory pages, and the queue is FIFO features, and the algorithm is the same, so whe
