WebFeb 22, 2024 · Here is the algorithm : Initialize two pointer variables to find the candidate elements in the sorted doubly linked list. Initialize first with the start of the doubly linked list i.e; first=head and initialize second with the last node of the doubly linked list i.e; second=last_node. We initialize first and second pointers as first and last nodes. WebSep 8, 2024 · Given a Singly Circular Linked List. The task is to delete all nodes at even positions in this list. That is all starting from the second node delete all alternate nodes of the list. Examples : Input : List = 99->11->22->33 Output : 99->22 Input : List = 90->10->20->30 Output : 90->20. Note: Linked list is considered to have 1-based indexing.
