In short: the lead node can make any node in the linked list be inserted and deleted equally through a fixed head. The linked list without a head node needs special processing when inserting or deleting the 0th position, and finally the head point must be changed. Theis to insert and de...

How to insert node at the end of a Circular Singly Linked List in Java(上)。听TED演讲,看国内、国际名校好课,就在网易公开课
To insert a node in a linked list we first need to create the node, and then at the position where we insert it, we need to adjust the pointers so that the previous node points to the new node, and the new node points to the correct next node. ...
