You can search an element on a linked list using a loop using the following steps. We are finding item on a linked list.Make head as the current node. Run a loop until the current node is NULL because the last element points to NULL. In each iteration, check if the key of the ...
Given a pointer to the head of a linked list, insert a new node before the head. The value in the new node should point to and the value should be replaced with a given value. Return a reference to the new head of the list. The head pointer given may be null meaning that the ini...
