Description: 题目：设计一个请求页式存储管理方案，并编写模拟程序实现
具体要求：
1、产生一个需要访问的指令地址流，为不失一般性，可以适当地（用人工指定地方法或用随机数产生器）生成这个序列，使得 50％的指令是顺序执行的。25％的指令均匀地散布在前地址部分，25％的地址是均匀地散布在后地址部分
2、 页面淘汰算法采用 FIFO页面淘汰算法，并且在淘汰一页时，只将该页在页表中抹去。而不再判断它是否被改写过，也不将它写回到辅存
3、产生一个需要访问的指令地址流；指定合适的页面尺寸（例如以1K或2K为1页；指定内存页表的最大长度，并对页表进行初始化
4、每访问一个地址时，首先要计算该地址所在的页的页号，然后查页表，判断该页是否在主存。如果该页已在主存，则打印页表情况；如果该页不在主存且页表未满，则调入一页并打印页表情况；如果该页不在主存且页表已满，则按 FIFO页面淘汰算法淘汰一页后调入所需的页，打印页表情况 。逐个地址访问，直到所有地址访问完毕

The algorithm uses pages out pages out of FIFO algorithm, and eliminate one, the only page in the page table to erase.
