内存是计算机系统中储存指令代码和各种数据的主要部件，如果内存短缺或者管理不当，将导致整个系统反应迟缓，甚至崩溃。所以，建立稳定、高效的内存管理策略是一个很重要的且必须面对的问题。现代的操作系统中运用位图、链表等多种手段和算法来管理内存。伙伴算法(Buddy System)是一种经典的内存管理算法。在Unix和Linux操作系统中都有用到。其作用是减少存储空间中的空洞，减少碎片，增加利用率。

本程序模拟了内存管理的过程-Memory is stored in a computer system code and instructions of the main components of data, if the memory shortage or mismanagement will lead to the whole system slow to respond, or even collapse. Therefore, to establish a stable and efficient memory management strategy is a very important and must face. Modern operating systems use digital maps, list and algorithm means to manage memory. Partners algorithm (Buddy System) is a classic algorithm for memory management. In Unix and Linux operating systems are used. Its role is to reduce the storage space in the hollow, to reduce the debris, increasing the utilization rate. This procedure simulated the process of memory management
