已知一个双向链表，从第二个元素开始已经呈递增有序，请编写一个算法把第一个元素删除且插入到适当位置，结果链表仍然有序（设表无头结点）

主要是定义一个双向链表，随意输入几个数字，把第一个数字插进去，条件的是呈递增有序，把第一个元素删除！

-Known to a two-way list, from the beginning of the second element has been increasing in an orderly manner, write an algorithm to delete the first element inserted into the appropriate position and the results list is still in an orderly manner (without a head table set-node) is the definition of a two-way linked list, enter the number of random numbers into the first number, and the conditions that were increased in an orderly manner to the first element to delete!
