Explanation: In the figure above, there is a sorted circular list of three elements. You are given a reference to the node with value 3, and we need to insert 2 into the list. The new node should be inserted between node 1 and node 3. After the insertion, ...

Hi All, I would like to know how it is possible to insert a node in a linked list without using a temp_pointer. If the element is the first element then there is no problem but if it is in between then what is the best solution.
