clock算法是内存分配的一种！结合LRU和FIFO！-clock

四种置换策略OPT LRU FIFO CLOCK的c++实现-OPT LRU FIFO CLOCK

设计和实现关于内存管理的内存布局初始化及内存申请分配、内存回收等基本功能操作函数，用了最佳替换算法Optional、先进先出（FIFO）页面置换算法、最近久未使用(LRU)置换算法、Clock 算法（也叫Second Chance 算法）-Design and implementation of memory layout application initialization and memory allocation, memory recall about memory management

操作系统的存储管理实验，里面有FIFO算法和LRU算法，还有CLOCK核心算法(The storage management experiments of the operating system include the FIFO algorithm and the LRU algorithm, and the CLOCK core algorithm.)
