1・能够创建链表，只须输入数据便能自动生成升序排列的单链表；
2・能够把已存在的两个自动升序的链表合并成一个链表，并保留其中的相同元素；
3・有友好的人机卷面；-To create one list, only the input data can be automatically generated single-linked list in ascending order 2 can has been in existence for two automatic ascending the list into a list, and retains the same elements 3 have卷面friendly
