The code implements the circular Unidirectional link list (the tail pointer points directly to the head pointer, there is no empty node in the middle), and the operation of successive repeating elements is removed.For example: 1 (head)->2->2->3->3->1->1 (head) after the removal of the result is 1->2->3, notice that the tail of 1 also to remove one.The time complexity is O (N)//Space complexity is O (1)//code as follows: #include Copyright NOTICE: Thi
