可变分区回收算法。将回收的内存插入到自由主存队列中,供下次分配内存时使用.在本模拟程序中,自由主存队列的排序原则是按地址排列的-Variable partition recovery algorithm. The recovery of memory inserted into the free queue in main memory, the memory allocated for the next use. In this simulation program, free main memory queue sorting principle is arranged by address
