 　　模拟成组链接法的原理；

设系统具有7个可用磁盘块，每组3块。

编程模拟实现成组链接法。输入请求的磁盘块数，模拟成组链接分配；输入回收的磁盘块号，模拟成组链接回收。

-Simulation into a set of links 　law principles　based system with 7 free disk blocks, each 3. Programmed into a set of links to achieve simulation method. Enter the requested number of disk blocks to simulate group-link distribution　enter recovery disk block number, into a set of links to simulate recovery.
