采用伙伴算法管理空闲区，并增加已分配区表。

可以建立7个链表 ，分别来管理大小为210、 29、 28、 27、 26、 25、 24 块的空闲区，每块大小为16个字节。假定内存一开始有一个210的块和一个26的块，其它为空。实现内存的分配不回收。每次分配和回收后，都要显示程序运行结果。

每次分配和回收后，都要显示。-Free zone management by partners algorithm, and to increase the allocated area table. Can create 7 list, respectively, to manage the size of 210, 29, 28, 27, 26, 25, 24 of the free area, the size of each block of 16 bytes. Assume that there is a memory of a block and a 26 210 block, others are empty. Not achieve the allocation of memory recovery. Distribution and recovery time after the run results to be displayed. After each allocation and recovery should show.
