开发一个多线程程序同时对一个链表进行节点插入。

（1）要求算法正确

（2）该系统要求使用头插法，插入结果正确，并输出结果。

（3）要求模拟出多线程程序资源共享问题。在本程序中体现为链表节点的丢失。

（4）给出正确的链表受到保护的实现。要求使用线程同步机制。

-The development of a multi-threaded program while a linked list node inserted. (1) requires the correct algorithm (2) The system requires the use of head interpolation method, insert the result is correct, and outputs the result. (3) requires that the analog of a multithreaded program resource sharing problem. In this procedure embodied list node is lost. (4) is protected to give the correct implementation of the linked list. Require the use of thread synchronization mechanism.
