本代码提供对动态数组的支持，在内存中程序将数据分块存放，避免了大块内存的申请。同时，与普通的双向链表不同，本代码提供了对内部数据的快速索引，大大提高了数据访问速度。-The code provides for dynamic arrays support program in memory data block stored, avoiding large memory applications. Meanwhile, different from ordinary doubly linked list, the code provides a quick reference to the internal data, greatly improving the speed of data access.
